very high, he obviously is skillfull on the ball and many west ham fans think he is better than just sitting as a DM, we have just lost gundo, potentially could lose berny and mahrez and kev has half a season at best in him.
Pep could see him expanding from the role he plays at west ham into a more box to box or forward midfileder, he could potentially play 80-90% of our games depending on what we are buyng him for.
This is why Pep is a genius, he doesn't buy a player for just what they do, but what they could become and evolve into.
