Chelsea winger Eden Hazard is reportedly a doubt for Saturday's Premier League clash with London rivals Arsenal at Stamford Bridge.
The 26-year-old picked up a knock during the 3-0 win over Leicester City last month that forced him off with 11 minutes remaining, and he has also been withdrawn early in Chelsea's last two games against Hull City and Liverpool.
The Belgium international was seen pointing to his hamstring as he came off during Tuesday's draw at Anfield, but was not limping when boarding the team bus and yesterday trained as normal with the rest of the squad.
Hazard is expected to start against the Gunners, but could be in line for a rest sooner rather than later amid concerns that the niggle is affecting his performances.
David Luiz is also thought to be playing through the pain barrier having suffered from discomfort in his knee since being on the end of a rash challenge from Manchester City striker Sergio Aguero two months ago.
