Advertisement Advertisement Hostile atmosphere at the Olympic Stadium It's already been mentioned but the atmosphere is very hostile in Barcelona. It's going to be interesting to see how loud it is inside the ground when it gets going. A huge night ahead. Nelson Vivas: 'We think it’s going to be tough' Nelson Vivas, Atletico Madrid assistant coach, speaking to Movistar: We think it’s going to be tough; intense, a hard-fought game, for at least 90 minutes with the possibility that there could even be extra time. But hopefully not, hopefully we can resolve it earlier. I’m confident in the team’s momentum and in its performance. Kick-off closing in Is everybody getting excited? We are less than 15 minutes away from kick-off now, the teams have warmed up, the stadium is filling up, and it's nearly go time. This is when anticipation for the night goes through the roof. Which two sides will progress? Right, we're nearing kick-off, so you know what that means - prediction time. These two ties are so hard to call, but we want to hear what you think, which two sides will progress to the semi-finals? I'll start, I'll go with Barcelona and Borussia Dortmund... Let us know your predictions in the comments. Barcelona making despicable chants Pete Jensen, Mail Sport, at the Olympic Stadium: Six goals for Kylian Mbappe so far in this Champions League. Only Harry Kane with seven has scored more. Added spice tonight because Barcelona fans know he will almost certainly face them as a Real Madrid player next season. Plenty of chants against him and Real Madrid (the Clasico is Sunday) outside the ground. Despicable chants of 'Die Vinicius' too. Can Pedri make an impact? What a player Pedri is! When the 21-year-old midfielder came on last week, he changed the match within minutes with a delightful lofted assist for Raphinha. Barcelona's maestro can be simply majestic and it is a huge boost for the side that he is back in the starting 11 tonight. He will cause PSG a lot of problems. 'Yellow Wall' ready and waiting Wow, what a sight to behold. It seems like all the fans of all the clubs involved tonight are doing all they can to pump up their teams. It's not often you see a stadium practically full this long before kick-off. It's going to be loud. PSG seeking comeback against the odds 'La Remontada', the night Barcelona created history by thrashing PSG 6-1. We all remember that night. Well, PSG are seeking revenge and want their own version of that tonight, albeit less dramatic. They look like they mean business, they believe. Do they have what it takes to turn the tie? 'Hostile pre-match atmosphere aimed at Dembele' Pete Jensen, Mail Sport, at the Olympic Stadium: Hostile pre-match atmosphere aimed at Ousmane Dembele. Few 100 dollar bills with 'Judas' and his face on them in circulation outside the stadium. The former Barcelona player always seems fairly oblivious to what is going on around him so let's see if it affects him tonight.
