Mustafi.

[PSRB]

But he seems to make criticial ones, sc.

AND. the same critical ones. Over and over.

Must notably going to fúcking ground too quickly. leading to all sorts of bad nonsense

he makes the sort of mistakes that you don't get away with in the PL. That said, I do agree with sc, I said it on Twitter the other day, there is a very good defender there, most of the time.
