You overrate the importance of players being good on the ball. I also hoped Umtiti could be decent for us and help us play from the back. But his blunders overshadow it. Comical stuff, worse than Lenglet. And that's hard this season.
Lenglet is good on the ball too, by the way. Bellow Umtiti, but good..
I think they are both a bit subpar on the ball, in ther decisions, for Barcelona. I never had very high hopes for Umtiti, but don't think we should be too hard on him now.
I think the first criteria for a Barcelona CB should be that they are good on the ball. After that they should look for speed, 1v1, and concentration. But with the current way of playing everything changes, obviously.
My point there though was that 4 mistakes can happen, surely Mingueza could've been the one caught out by 4 mistakes in the same games, were the opponents to capitalize there instead.
