Tough selection. Not only we have Madrid, but we also just had one of our best match of the season. Against Madrid, Rico cannot play (Vinicius would eat him alive), so we might want to give Stones some minutes and Akanji plays as a RB.
We should rest Bernardo for Kovacic, and then maybe Foden for KDB. Give Bobb a starting chance. Alvarez/Haaland is a really tough decision, because I imagine Haaland will start against Madrid, but I would prefer Alvarez for his pressing. Hopefully we can get a 2-3 goal advantage by the 60th min and rest Rodri.
