Chelsea are sweating on the fitness of defender Andreas Christensen, after he was sent home by Denmark with question marks surrounding his physical state.

Christensen joined up with the squad for the upcoming international friendlies, but was soon sent home as his manager found him fatigued and not in the right condition to play.

Danish boss Age Hareide is quoted by The Sun as saying: "Andreas Christensen has been sent home to London.

"We do not want to take any risks with him.

"We have called up Peter Ankersen and Lasse Nielsen, so we are adequately covered in defence.

"I cannot say exactly what is wrong with Christensen, but it is a little fatigue.

"It's not serious, but it can be. It is a bit frustrating because we would have liked to trial him in both central defence and as a defensive midfielder."
