The only player I’d have in the United defence for Liverpool is Alexander Arnold, and even then Wan Bissaka is very good defensively.
Chelsea play a back 3 so is slightly different but even then they will probably end up with the best defensive record in the league this season and have been great since Tuchel arrived.
Walker Stones/Laporte Dias Zinchenko. The only player getting in there from Liverpool is Robertson.
Id throw a blanket over all the keepers as similar standard, De Gea has had poor form recently but Allison was teeing up goals for City only last season.
Alexander Arnold and Van Dijk are poor positionally, they just have a lot of pace to bail them out and in Van Dijk’s case rely on being overly physical. Matip is in my view their best defender positionally but he’s not often fit. Robertson is annoyingly good when the PEDs are flowing. He looked bang average last season though when they weren’t.
Watch them in nearly any game and they’ll cough up two or three absolutely gilt edged changes for the opposition. They just don’t concede them though, it’s not good defending, just terrible finishing time after time after time. Even just consider our games against them, we’ve had Gomes Mina and Coleman all put headers from a yard out straight at the keeper, Tosun and DCL have missed open nets from inside the box, and Davies scuffed his onto the post. That’s just us. Like I said City have missed multiple penalties against them and Mount missed a sitter at 1-0 up for Chelsea. Teams just miss easy chances against them, always have done. The goals we conceded against Burnley last season, all three from Raphinha, the headers from Callum Wilson, even the one from Armstrong this season for Southampton, you just don’t see finishing like that agaisnt Liverpool hardly ever.
