Eden Hazard is to undergo scan on Monday, after suffering an injury in the 3-0 win over Crystal Palace.
On his return to the starting XI, Hazard appeared in pain after playing a shot in the ninth minute, he was substituted.
“Hazard has a little problem with a groin muscle,” the trainer said at his post-match press conference. “We will see more with an MRI scan tomorrow.”
Chelsea responded impressively from the loss of Hazard to record their first away league win since August.
