I definitely think we need a right back, Zab as much as I love him clearly hasn't got the boundless energy he once had and Sagna is solid but offers very little attacking threat these days.
Then I think it's one, maybe two natural wide players depending on where De Bruyne prefers playing and also if Pep feels like he can get any consistency with Brandon Barker who I think has everything technically but others who see him far more regularly seem to believe he's a bit soft and goes missing too often. Sterling will be brilliant under Pep, given freedom to run at players again in the final third but Navas has to go, maybe it's just confidence with him too but I just don't see any potential in him.
There's no place for a fast winger who can't cross or score. All our front three or four players need to be scoring double figures. We need a front three like Barca. I hope Sterling finds his shooting boots.
