Chelsea defender Ben Chilwell could be a huge doubt for the World Cup after he limped off in the final moments of Chelsea's Champions League match against Dinamo Zagreb.
Chilwell pulled up clutching his hamstring in the fourth minute of added time before he was helped off the field by the Blues medical staff after the full-time whistle.
The 25-year-old had just recently recovered from a long-term knee injury but could now miss more action including England's World Cup campaign with another injury.

Playing at left back, Chilwell had put an impressive performance for the Blues buccaneering up and back the wing as he was doing before his injury.
Graham Potter may have several other injuries to contend with as well as Denis Zakaria limped off while Cesar Azpilicueta also seemed to be in some discomfort in their 2-1 win over Zagreb.
Following the victory speaking to BT Sport, Potter said on the initial diagnosis that "it doesn't look good", Chilwell will likely have to see a specialist to determine the damage but the reaction of teammate Mason Mount who looked away in shock when speaking to Chilwell and the tone of his manager implies the injury is serious.
