Ancelotti has been reunited with his former Real Madrid midfielder this season.
"James wanted to play. He was desperate to play, to find a club that believed in him, and to find a coach that trusted him. I'm sure that when James feels accepted, loved, he will have great performances," Ancelotti explained on the podcast 'Men in Blazers'.
"James is not a physical player. He is technical and talented. You have to use him for his qualities. If I ask him to run the 90 minutes up and down he will not do it , but if I ask him to have good ball possession, put good passes, score goals, he will be available to do it."
