Not when he is shit. Look at the quality in the starting eleven. He shouldn't even be on the bench. One weak link is all it takes to lose a game. Fact.
Fuck off?
Delph and Danilo are also utterly uncapable of defending but Zinchenko is a kid- what're their excuses?
At least he can pass a football whereas the other two look terrified of crossing the halfway line when deployed at left-back. Get behind him, I imagine Pep would know better if he was up to it than you.
