I'm sorry but whilst we obviously do need some quality signings, we have Fernandes, Pogba, Rashford, Martial, 80m Maguire etc on that pitch, and yet time and time again they all look garbage, so much space on the pitch, we're leaving gaps all over the place and this was before the red card. It's Cardiff/Molde level of tactical play. The only times we've played well under him can be summed up in two spurts, when he first joined and feelings were riding high, and then when Fernandes came in, but since then Fernandes has slowly been dragged down to bottom level along with the rest.
Buy any CB you want, Upamecano, whoever, after a while I guarantee they'll become shite here.
