Madrid are fearful of the Etihad, even his coach and players have said they think it is the toughest place away. That plus the last two matches here where we could literally beat them for 5+ goals is a huge mental advantage. They know they have to win by at least 2 goals in Bernabeu.
I think Pep will go as defensive as he ever has, and I would too. The mental game is ours. I would go Rodri- KDB- Kovacic- Bernardo- Grealish- Foden as false 9 changing constantly with KDB. If we keep a draw, I would let Haaland in around the 60 min when they surely will try to go for goals and leave plenty of space behind.
Defensively it should be Akanji vs Vini for sure (unless Walker recovers). Dias and Stones and then Gvardiol if he is fit. If he isn't, I would prefer Lewis as a LB than changing Akanji.
