Chelsea boss Graham Potter admits he's unsure of N'Golo Kante's playing return.

Kante last played for the Blues in August during their fiery 2-2 draw with Tottenham.

But niggling injury issues have left him on the sidelines.

Chelsea boss Potter provided a fitness update on the midfielder - and admitted things were "worrying".

He said: "Again he's due to see a consultant at the weekend. It's a setback so it's not good news. But anything other than that, at this stage I can't give you any more.

"Historically, there are things which have happened which are a concern and we need to get the bottom of that.

"It's a setback in the last stage of his rehab so again that's worrying. But all we can do is get the right diagnosis, the right consultation and then try help him get back to full fitness and enjoying his football."
