Chelsea playmaker Eden Hazard will have a scan on Monday to determine the seriousness of the groin injury he sustained during a 3-0 Premier League win at Crystal Palace.
Having returned to the Chelsea starting XI in the team's previous two matches following a hip complaint, Belgium international Hazard pulled up awkwardly after taking a shot in the ninth minute at Selhurst Park on Sunday.
"Hazard sprained his leg, he has a little problem with a groin muscle," Chelsea boss Guus Hiddink told a post-match news conference.
"We will see more with an MRI scan tomorrow."
"Mikel played very well, he's the ideal player to bring balance to the team. He knows the game very well and how to cope.
"We know there is a lot of quality in the squad, not just in the starting XI. When they get the ball they can play."
"Do not go over the top. It is the first win after a worrying period with two draws so the team desperately needed the win and it was convincing," he said.
"Everyone knows we have a lot of quality in our team, but sometimes champions have a tendency to be complacent and it can be difficult to get back and then wonder why we were champions.
"There is a long way to go, mathematically the possibility of Champions League is still there. The league is so strong but as long as we play like we did today I will be happy."
