Former Liverpool star Peter Crouch has expressed concern over Feyenoord manager Arne Slot replacing Jurgen Klopp at the end of the season.

Mail Sport revealed on Friday that the two clubs have agreed a deal for Slot to make his debut Premier League bow at Anfield, while the Dutch side are set to receive up to £9.42m in compensation for their departing boss.

Slot was previously in the frame to join Tottenham last year before Ange Postecoglou was given the managerial role, but is now on the verge of being appointed as Liverpool's next dugout chief.

The Reds were previously favourites to replace Klopp with former player Xabi Alonso before the Spaniard decided to extend his stay at Bayer Leverkusen after winning the Bundesliga title.

Crouch has now revealed he expects it to be 'difficult' for the incoming Slot but praised the 45-year-old's style of 'heavy metal football'.

'It's going to be difficult for him to step into Klopp's shoes, I don't envy him. the selection process probably centred on his style of play and character,' Crouch told TNT Sports before Liverpool's match against West Ham.

'Interestingly, a lot of the murmurings are similar to when Klopp came. He plays attacking, heavy metal football. He's a big character, develops players. Very similar.

'If someone came in and tried to play men behind the ball, changed the whole philosophy [it might not work]. 

'What they've done is get someone who plays a similar way with fresh energy and impetus to take them onto the next level,' he added.

Liverpool defender Andrew Robertson was amongst the first players to recognise Slot's impending arrival, but admitted full focus was on giving Klopp a fairytale send-off with another Premier League crown at the end of the season.

The Reds need both Arsenal and Man City to drop points during their remaining games to stand any chance of winning the English top-flight and must win all of their final four fixtures.

'It's obviously something that we can't really focus on just now,' Robertson said after being asked about Slot.

'There's been a lot of talk over the past few days and it looks as if it's nearly finalise if not finalised. 

'But we have to focus on this season and giving this manager our all until the end and giving him the farewell he deserves for what he's one for this club,' he added.
