Chelsea boss Thomas Tuchel is happy playing Reece James at centre-half.

Tuchel admits he's unsure of what James' best position actually is.

He said, “I think the back three is less demanding physically in comparison to the wing-back position. Given he comes back from a long injury, a muscle injury, with the risk of a re-injury over so many weeks, it is a bit of an advantage to have him in a back three because it is less demanding physically.

"This is the next step: how many games can he play at wing-back if he plays wing-back during a season, and at a level where he is reliable and decisive? It [right centre-back] is less demanding physically in terms of accelerations, long acceleration, and high speed on a back three.

"That helps us have him on the pitch for more minutes. That's why he plays in there. He can play both positions brilliantly. We only have him once so we need to decide but that's the reason at the moment. I love him in both positions. I'm not sure (what his best position is)."
