I would like to see something like that:
Ederson
Walker, Stones, Dias, Laporte
Rodri
De Bruyne, Gundogan
Bernardo, Haaland, Grealish
With the exception of Walker (who has a critical job of taking care of Vinicius), that's a technically sublime side capable of dominating Real Madrid. Additionally, we will have strong defensive support from Jack and Bernie on the wings. Kevin and Gundo should be fine in the middle up against the likes of Modric and Kroos, especially with Jack and Bernie supporting them, and Rodri providing the necessary protection defensively. Finally, I picked Laporte over Akanji as he is technically superior, less rash, and more experienced at this level than Akanji.
Julian, Phil, Riyad available to come on depending on the result and the general situation.
