Ben Chilwell has become the latest World Cup doubt after he suffered a hamstring injury during Chelsea’s final Champions League group game against Dinamo Zagreb on Wednesday evening.

The England left-back pulled up clutching his left hamstring in the closing stages of Chelsea’s 2-1 victory at Stamford Bridge and was forced to leave the pitch with the help of two of the club’s medical staff.

As he left the pitch, television cameras caught Chilwell telling his Chelsea and England teammate Mason Mount that his hamstring had ‘popped’.

When asked about the severity of Chilwell’s injury, Chelsea manager Graham Potter said: ‘It doesn’t look positive.

‘It’s a hamstring. We will have to scan it and see how it is.’

Chilwell is now a major doubt to be fit for the start of England’s World Cup campaign, which begins with their first game in Group B against Iran on November 21.
