I understand dropping Doku simply because he's perpetually injured, but I don't understand dropping Grealish just to put Nunes out wide. Eze will go past Gundo/Bernardo as if they aren't there. Start Nunes next to Bernardo and put Grealish out wide.
Pep prioritizes the Juve game, it's that simple. He's likely to sub on Doku and Grealish after the break.
