Thomas Tuchel ecstatic with James’ versatility on the pitch.
The German coach is clueless on whether James is a better right-back or a right centre-back.
The defender who joined the Blues at the age of six has been outstanding for the Blues in the past few seasons.
He has missed two months of football due to a hamstring issue since the start of the year but is now available for contention.
“He can play both positions brilliantly, but we can only select him once,” said Tuchel.
“I think that the back three is a little bit less demanding physically, in comparison to the wing-back position and given that he comes back from a long injury, a re-injury over so many weeks.
“It’s a bit of an advantage to have him in the back three because it’s less demanding physically.
“It’s a bit less demanding physically in the back three in terms of accelerations, long accelerations and high speed.
“That helps us to have him on the pitch for more minutes, and that’s why he plays in there. So we need to decide, but that’s the reason at the moment.”
