Unrealistic:
Kimmich - Starts in midfield, and if Casemiro comes good we can play Bruno on the left, make him the best sub in the league (has the frantic enthusiasm that good subs often do) or if one of Dalot or Varane is out or resting you'd have Casemiro at CB above our options (filled in there for Madrid when needed) and Kimmich available to play RB. Basically John O'Shea if he was a top 10 player in the world.
Benzema - Think he'd fit the way Ten Hag wants to play or be his usual threat on the counter, so I went with him over Haaland as I'm not sure we make enough chances to break down teams, though with Kimmich and our next player we would
Vinicius - Starts on the left, Sancho can fight for a place with Antony and we'd have a sub who can come on and create against tired fullbacks or their replacements.
Realistic:
Maignan - Looks great whenever I watch them, good on the ball and even throws it out well. I think Tomori and Kalulu might be a little overrated and him underrated for winning the league. I tend to watch Tomori close out of natural England curiosity and the fact that I understand why Southgate hasn't put him in the starting lineup is saying something considering his mediocre competition. He might not push the move, but could Milan turn down 40M when they could probably buy a decent replacement for 15M and sign a proper RW (Messias and Saelemakers are backups for a team trying to win Serie A more than once and make the CL knockouts) with the 25M left?
David - Very good goalscoring rate for his age, good in link up play and works really hard. The risk is that he might be average against teams sitting deep, but we don't look anywhere near ready to peg teams back and I think he could be a Jesus type as he matures into his mid 20s and be really annoying to play against.
De Jong - because Ten Hag wants him and I love watching him and we'd have Eriksen and Bruno and him to play in 2 spots and consistent midfield play for the first time since Scholes, Carrick and Fletcher roamed the earth. I do think there's some risk with him in the Prem, though Moussa Dembele also held the ball a long time as a #8 and was pretty damn good.
Other candidates I'd be excited for are Araujo, who Xavi might eventually look to replace in the starting lineup with a better passer but would be fantastic in the Prem and as the long term replacement for Varane. Looks like Vidic with pace at his best. Vlahovic, would be unrealistic but maybe Juve will fall apart. Not inconceivable if Chiesa stays hurt and Locatelli keep struggling. If they miss the CL this year and next, would he look to leave or they look to sell him for 100M and rebuild their team with 3-4 new players?
