All the sub players NEED to play, I'd be shocked if we didn't start any of these based on Pep's comments about being fresh for the premier league. My guess is this:
Ortega
Rico
3 defenders who are fit
Phillips
Nunes
Doku
Bobb
Gomez
Haaland
Please rest Alvarez he runs like crazy and played non-stop. Haaland's game is such that he can play 90 mins every game and I don't think he'd be that tired because he doesn't press as crazy as others on the team.
Gomez should be given a chance on the LW again, putting Doku RW.
Rico is guaranteed to start, I put him RB as its more natural for him, and Doku can cut in, but wouldn't be surprised if Pep plays him LB, and plays a defensive player RB.
