This is fair. I think Cleverley is the sort of lad who plays well in a better side where there is a spot he can blend in too. The start of last season, when Lukaku, Barkley and Deulofeu were flying and he could just fill in solidly was perfect for him. When their form dipped he wasn't good enough on his own to win us games, or rugged enough to play deeper.
I had hoped he could follow an Adam Lallana style transformation under Koeman. Prior to Klopp Lallana resembled Cleverely. Some international experienced but lacking a yard of pace and a goal output. However a hard worker, good at pressing, could chip in with goals and assists if not being prolific. I think Lallana is just that bit more physical though and is able to play in a midfield 3.
