With Araujo being out against PSG, we desperately need speed in the center so I agree with Koeman giving Mingueza game practice as CB. Firpo against Papu could be fun. Or is he surprising us and Firpo starts as CB? We will see, but I can't blame Koeman given the lack of options at RB and CB.
Maybe Lenglet is still having issues with his knee.
Pique, Fati, Coutinho, Araujo, Dest, Roberto, Pjanic and Braithwaite all injured. Crazy.
