Cole Palmer is a doubt for Chelsea’s Premier League game against Arsenal on Sunday after limping out of Old Trafford at the weekend with a knee injury.

Head coach Enzo Maresca called the challenge from Manchester United defender Lisandro Martinez on the 22-year-old during Sunday’s 1-1 draw "not a normal one,” and admitted there is a risk the England international will miss the London derby.

Palmer has not trained since the incident, which occurred in stoppage time and earned Martinez a yellow card, and he is not eligible for Thursday’s Conference League game at home to FC Noah.

"He didn’t train (Tuesday), we’ll see today if he is able to train with us,” said Maresca.

"Hopefully he’ll be ready (for Arsenal) but we need to wait and see, then decide.”

Asked whether there was a chance Palmer could miss Sunday’s game at Stamford Bridge, he said: "Yeah, for sure. He didn’t train the last two days. The tackle it’s quite clear was not a normal one. But hopefully he can be back.”
