I rarely do this, but in this case I will. I absolutely said exactly this above with regards to Bentaleb, who was clearly unsure of what Dembele was, or wasn't, going to do and where he was going to be. It impedes the partnering CM massively, and I think Bentaleb was often left in a no man's land of wanting to push on into spaces but not being sure that Dembele would hold. We saw this with the first goal, when Dembele was caught GHod knows where. As the senior prof,,it is on Dembele to be clearer IMO...
Sandro - Dembele never (or at least very rarely) have those issues. This rests at least as much on Sherwood as on Dembele. Either don't play Bentaleb or make sure the other players are aware of their duties.
