mustafi is fine, sounds like he was wank tonight but christ maybe if bellerin could defend to save his life then mustafi wouldn't need to be busy telling him what to do.
the cb's are the least of our problems, when the main two were on we conceded 1 right? Gabriel is a horror show so not surprised we let in 4 after he came on, 3 defenders who can't defend and mustafi is left to do everything even though he's more of a vermaelen type.
