Chelsea midfielder N'Golo Kante had to be substituted just 10 minutes into Chelsea's Premier League clash with Manchester United on Monday.
After taking a knock, he was unable to continue and had to be replaced by Mason Mount:
The Frenchman has been a key fixture in the Chelsea side since he joined the club in 2016, through the managerial reigns of Antonio Conte, Maurizio Sarri and now Frank Lampard, and it will be a big concern if he has to face time on the sidelines.
Injuries have troubled Kante on several occasions already this season, with an ankle problem causing him to miss four games across August and September.
