Don’t be surprised with only two changes from last night, Ortega and Laporte followed by 5 changes (2 and 3) early in 2nd half.
There'll be at least 5 changes, maybe more.
The likes of Alvarez, Walker, Laporte, Ortega, Mahrez, maybe Foden are guaranteed to start. Add to them Phillips, and one from Gomez, Rico and Palmer.
Pep will want to rest the midfielders, in particular Rodri, Kevin and Gundo. Bernie is extremely fit and may start in midfield alongside Phillips and Foden/Palmer. Midfield is bound to be a bit experimental anyway. Would be mad to risk injuries and fatigue against SU.
IF we aren't winning with 30 minutes to go, then Haaland, KDB and Grealish, maybe Rodri will be brought on. Better to use them from the bench against tired legs in the 2nd half.
