Jack as a Rodri replacement makes complete sense. It pains me at times seeing him out wide just playing the ball backward.
Pep's played Bernardo at fuckin LB, so I've no idea his aversion to Jack in the middle. Gundog is not the player he was during his final season. Dunno if he just needs time to regain his form, but he just seems a shadow of the player who left for Barça.
As for Nunes, he never did & still doesn't make sense as a City signing. However, he's here & I suppose he offers a chance to rest & rotate players in less high profile games.
