Cristian Romero nearly hits straight back!

The Argentine defender throws Martin Odegaard to the flow and meets the Spurs corner, but his header flashes wide.

That was very close, but would it have been called back for a foul if it had gone in?

I guess we will never know.

The goal means that Tottenham have now gone 13 games without a clean sheet at home.

They had started the game well, but have presented Arsenal with a gift just like they did last season.

Arsenal hit the front!

What did I say again? Arsenal may not have started well, but they have taken the lead in the North London derby.

The Gunners are the kings of the set-piece and they score from one again as Bukayo Saka's corner is headed into his own net by Pierre-Emile Hojbjerg.

It's a great header, just as the wrong end...

Kai Havertz puts the ball in the net, but the flag is already up.

Weren't used to seeing the flag go up so quickly, they usually wait just in case, but not this time.

Martin Odegaard was offside in the end, so it's the correct decision.

Spurs have started really brightly.

Arsenal can't seem to get the ball clear and Spurs win the ball back before James Maddison sends a strike over the bar from distance.

This is not an Arsenal performance we have become accustomed to of late, not at the races yet.

Thomas Partey goes down just outside the box and wins a free-kick, the Spurs players and fans aren't happy about it.

However, the free-kick is fired straight into the wall by Leandro Trossard and the crowd are cheering again.

We've had our first shot, well, I guess the term shot is debatable.

Timo Werner drives down the lefthand side and fires an effort straight into the gloves of David Raya.

In all honesty, it may have been just a poor cross, but I will give him the benefit of the doubt.

That was very unlike Arsenal.

Thomas Partey has the ball nicked from his toes by Rodrigo Bentancur and Spurs are on their way.

Luckily for Partey, his teammates bail him out, but that was not a good moment for him.

Spurs have started the brighter of the two sides.

Sami Mokbel, Mail Sport, at the Tottenham Hotspur Stadium:

An electric atmosphere here in North London today. Huge stakes, for both clubs. Already a thunderous and full-bloodied start. One of those days when you have to play the game, not the occasion.

It's already a little feisty.

Takehiro Tomiyasu and Dejan Kulusevski battle for the ball and there are a few afters.

The Tottenham crowd responds as they think Tomiyasu was a little too rough on their winger.

This could be one of those matches.

The Tottenham fans belt out 'Oh when the Spurs go marching in', I can tell you that it is very loud inside the ground.

Right, now the ball is rolling as Tottenham get the 195th north London derby underway.

A huge 90 minutes ahead!

Matt Barlow, Mail Sport, at the Tottenham Hotspur Stadium:

From a Tottenham perspective, a glance at the teams from this fixture in January last year illustrates the revolution taking place under Ange Postecoglou. Only four starting today who started last season… Romero, Hojbjerg, Son and Kulusevski.

The Tottenham Hotspur stadium is bouncing.

The Spurs fans roar as the two teams arise from the tunnel, they are certainly up for this one.

The music is getting me pumped up, let alone the players, but it is then ruined by the Premier League anthem... which you know I dislike.

Maisie, London: I have a sneaky feeling Tottenham may win this match...

Trevor, UK: Pretty obvious that Arsenal will win this, I'm going for 4-1.

Now we are nearing 2pm, I think it's time for some predictions.

Arsenal are the favourites, they are on fire at the moment, but Spurs on their day can cause anybody problems.

I think this could end up two apiece again, what do you all think?

Let me know your thoughts in the comments.

Mikel Arteta, Arsenal boss, speking to Sky Sports:

Against a very strong opponent in a very difficult ground. This is where we have to stand up and make it happen. The quality of the opponent, how tough it is to win in any ground, how difficult it is to win. We know that. We’re in a good moment and in rhythm. We had a few games to prepare. There’s a lot at stake and we’re ready.

On Thomas Partey starting again:

He’s a very important player for us. We have missed him for many months. He’s in great shape, his presence, his quality, physicality, experience. He’s a very important player for us. It’s a must-win and it’s been like that for many months now.

Is anyone else as excited as I am right now?

The two teams are just finishing off their warm-ups. I wonder how they are feeling, this is when the nerves and anticipation reach their peak.

The players will be itching to get going.

Oliver Holt, Mail Sport Chief Sports Writer, at the Tottenham Hotspur Stadium:

It's no surprise Arsenal are unchanged after their drubbing of Chelsea on Tuesday night. They were superb in every department at The Emirates but then a lot of teams have discovered that Chelsea are adept at making other teams look good this season.

Spurs will be tougher but we are at the stage of the season where only a win will do for the visitors. Anything else and it will be hard to escape the conclusion the title will be heading to Manchester City again.

The difference between Spurs' and Arsenal's defences is startling.

Arsenal sit top of the pile in terms of clean sheets this season, with 16. They could also become only the third team to record seven successive away clean sheets with another today.

Meanwhile, Tottenham have not managed a clean sheet in their last 12 Premier League home games. In fact, they have only kept two at home all season, the third-worst record in the league.

This could be key in terms of today's match.

It's not just Arsenal who have something to fight for.

As already mentioned, Spurs are embroiled in a tussle with Aston Villa for a place in the Champions League next season.

With Villa losing yesterday, Spurs' destiny is now in their own hands. Win all their games in hand, they go above Villa.

They are some very tough matches though, starting today.

Liverpool may be in this graphic, but we may as well rule them out of the title race.

There are only two horses left in the race as far as I am concerned, Arsenal and Manchester City.

If the Gunners win today, they will go four points clear, but with two games in hand. They simply have to win.

Manchester City face Nottingham Forest at 4.30pm, it's a massive day in the context of the title race.

This may all look very different in just a few hours time.

Ange Postecoglou, Tottenham boss, speaking to Sky Sports:

Very good opponent, but it is something we need to embrace. We rely on the stuff that has been good for us this year. We will try to get the crowd behind us and we will make it difficult.

If you want to be a club that is challenging for stuff this time of the year then all the games are going to be big, ultimately the reason why you're a footballer is to play in big games, it is certainly one of those.

Son Heung-Min, what a player.

The Tottenham captain has been a star at the front for Spurs for many years, and boy does he love a game against Arsenal.

Son has netted seven goals in the north London derby and only five players have netted more in all competitions in the fixture's history.

He will be hoping to add some more today.

Roy Keane, former Manchester United captain, on Sky Sports:

The pressure is on Arsenal to keep winning, but that's what it takes to win titles. They've got to keep that momentum going.

They have recovered well from their setback against Aston Villa, but with (Manchester) City behind you, they have to keep winning.

These two have been the key to Arsenal's success this campaign.

Martin Odegaard has shown why he is the Arsenal captain and has even been involved in six goals in his last six Premier League away games, scoring and assisting three each.

Meanwhile, if Bukayo Saka gets on te scoresheet, he will become the first English Arsenal player to score in both the home and away fixtures against Spurs in a league fixture since Ian Wright, 30 years ago.

Both players will have a major part to play today.

I was right, no changes from Mikel Arteta.

This side did rather well when they thumped Chelsea 5-0 in midweek, so nobody was expecting any changes.

Can they produce another masterful performance today?

Ange Postecoglou has named his first starting 11 in 15 days.

The Tottenham boss has made three changes from the side that was humbled 4-0 by Newcastle just over two weeks ago.

Ben Davies, Pierre-Emile Hojbjerg, and Dejan Kulusevski all come into the fray.

Richarlison returns to the bench.

Here they are!

Arsenal have arrived at the home of their biggest enemies ready for the big afternoon in front of them.

Team news is just a matter of minutes away, which 11 will Mike Arteta field today.

Surely, he won't make any changes, will he?

Gary Neville, former Manchester United defender, on Sky Sports:

It's a must (win for Arsenal). You look at what (Manchester) City are doing, they (Arsenal) put some pressure on them in midweek, and then City go to Brighton and do what they do.

You've just got to make sure that City go into that Nottingham Forest game knowing and feeling they have to win. They get let off the hook if Arsenal get beat here today. But, that's a tough ask.

Tottenham will be wearing a special warm-up shirt today.

The club's shirt will adorn a sign from Noah's Ark Hospice, their official charity partner.

A lovely gesture.

More of this, please?

These two sides served us up a cracker back in September, with Tottenham coming from behind twice to deny Arsenal all three points at the Emirates.

It was the North London derby at its very best and I have a sneaky feeling it could be a very similar game today.

Let's hope it is!

Tottenham fans, I want to hear from all of you!

Obviously, today's result will either harm or boost the chances of both of these happening, so I guess this question is more relevant for other games.

But anyway, would you rather see your side make the top four, but Arsenal win the league, or you the Gunners finish second and you miss out on the Champions League?

Let us know your thoughts in the comments.

You can tell it's a big game when there are already fans in the ground.

The atmosphere is building outside of the Tottenham Hotspur Stadium and some fans are starting to trickle inside.

The atmosphere is going to be electric today, both in the home and the away end.

I can't wait!

Ange Postecoglou, Tottenham boss, speaking on Friday:

It's just about making sure you embrace the challenge and try to tackle it in the way that got us into this position in the first place. From our perspective, we've had some inconsistencies and challenges this year, but when we've played well, we've played a certain way and gone about things in a certain way.

There's no point now when you get to the most important part of the year to shy away from that or change your approach. You've got to double down on it and focus on playing our football. That's a great measure for us because otherwise, you'll never know where you're short or whether you can be successful in doing it our way.

I bet Arsenal fans will start beaming when they read this post.

The Gunners' last trip to the Tottenham Hotspur Stadium was certainly a memorable one as they ran out comfortable 2-0 winners.

They took the lead within 15 minutes through a calamitous own goal from Hugo Lloris before Martin Odegaard netted a fantastic goal to secure a superb derby day win.

Today Arsenal have the chance to win consecutive league games at Spurs for the first time since 1988. If they play anything like they did in January last year, they will most likely achieve the feat.

This is a very different Spurs side to the one from last year, mind.

The Tottenham players arrived very early.

You know it's a big game when the players arrive in suits rather than the usual tracksuits.

The players are looking fairly relaxed, however, those smiles will soon be gone when they walk out onto the pitch. They will come back if they score, though.

A big afternoon in store.

Mikel Arteta, Arsenal manager, speaking on Friday:

More motivation (to win a derby), if anything, because you know what you can give to people, which is a lot of joy and happiness if we manage to win the game. When you have the chance to do that and it’s in your hands, you really want to make the most of it to try and make it happen.

We know about the rivalry, but I think you have to put that aside, you have to live the game with the intensity and passion that it demands. On top of that, we know what we are playing for so I don't think we need anything special because the game has got everything that you need as a player to go and enjoy it.

When these two sides meet, it’s normally the hosts that end the day with a smile on their faces.

Arsenal have only won two of their last 15 Premier League visits to Tottenham, however, one of those did come in this fixture last season.

The Gunners have also never in their entire history kept back-to-back clean sheets away at their bitter rivals.

You know what that means, we should expect goals.

Today’s match is huge, and even saying that is an understatement.

Both sides have so much on the line. Arsenal are in the midst of a title tussle with champions Manchester City.

The Gunners will be desperate not to suffer the fate of Liverpool, who have fallen at the final few fences, in what was a three-horse race.

Mix all that in with the fact that they face their bitter rivals Tottenham, and I think it would be fair to say this is their biggest match of the season. It certainly feels it anyway.

Spurs have a lot at stake as well. Ange Postecoglou’s side are still embroiled in a battle with Aston Villa for a spot in the four. They might sit seven points behind the Villans, but they do have three games in hand.

Pair that with their burning desire to ruin Arsenal’s title charge, then three points today would be a positive double whammy for them.

Writing all of that now has me fired up, so imagine how the players are feeling…

Did somebody say derby day?

Oh, it’s a big one today, huge in fact, it’s perhaps the biggest north London derby in 20 years. The implications of today’s result will massively affect both sides' seasons.

Arsenal are still more than in the hunt for their first Premier League title and a win today would put them four points clear of Man City, at least for a couple of hours.

Meanwhile, Tottenham would love to be the side that derails their bitter rivals title dreams, just like Everton did to Liverpool in midweek.

I bet the nerves have been jangling all weekend for both sets of supporters, this match means more than any other in their calendar. Now we are just two hours away from kick-off.

I for one cannot wait to see what happens in north London today and I’d put my money on that all of you are feeling the same.

So, with that in mind, let’s get cracking!
