France U21 coach Thierry Henry admits he concerns about Chelsea midfielder Lesley Ugochukwu.
Henry feels the youngster's development has stalled since his summer move from Rennes.
He said, "The problem is the same with Lesley. Even if the situation is different at Chelsea because in front of him there are players like Enzo Fernandez and Moises Caicedo.
"But he's not playing, and nowadays, these players don't even play with the reserve side to keep their rhythm.
"At the start of the season, you can benefit from the physical conditioning of the pre-season but the benefits fade. I hope he can continue to keep on course physically."
