I honestly don’t think Aurier would have the concentration required to mark running players so Sissoko has to nursemaid himI agree in a certain level he has his utility, but would't Aurier be more suited do mark running players also? You play Doherty and has to play Sissoko togheter to cover what he lacks. Well, it seems there's so many ways to fix this issue and we are not choosing the best, as our playing style during the games has been showing. But ok, we only has 4 players for 3 spots in the midfield and Sissoko will have to play anyway.
