Kulu has always said his preferred position is central MF. Ange resisted playing him there until he was forced too.
What?
Kulusevski was signed for Conte and played RW the whole time. He was firmly established a a RW in this league when Ange arrived.
The first time he got a chance to play centrally was last season, pretty early on in Age's first season. It was only this year that talk about moving centrally again came up and even now, some of his best games this season have been off the RW with the freedom to roam.
