There's no chance of this happening but this would be my ideal summer window. I'm discounting very unlikely transfers such as Kane and Osimhen but I'm (foolishly) assuming we get investment from somewhere.
Out: Maguire, McTominay, Fred, Martial, Elanga, De Gea.
In: Kim, Mount (since it seems likely) Rabiot, Kang In-Lee, Hojlund, Costa.
We'd have an excellent CB selection with a top class keeper who can play out from the back with good distribution. A midfield that is able to string a few passes together for once and a left wing choice who can take on players to great effect. We would have (in my opinion) one of the very best prospects at CF in world football and Rashford as backup. A great start and the spine of a team to challenge City with more investment down the line
