Has to be the Foden-Jesus-Sterling front 3 for me. It's exactly what we need in these big European games, absolutely incessant pressing, Jesus gives us so much control in midfield when he drops in, he carries the ball so well, Sterling's movement is second to none, there's loads of pace for the counter, and Foden has the spark that gets the team going.
Tore Real Madrid apart and would do the same to anyone.
I think the team picks itself - Ederson; Zinchenko, Dias, Stones, Cancelo; Rodri, KDB, Gundo; Foden, Jesus, Sterling. If he goes with Mahrez, I'll be beyond disappointed. He'll probably try to force Bernardo in, but it would be a mistake IMO.
