He flew to Barcelona on Thursday for further investigation on the problem and to undergo scans.

De Bruyne’s agent said: “The medical tests will clarify how serious or not the injury is.

“It happened in training while he was standing on his own – he wasn’t involved in a challenge.

“It was an unfortunate accident. He said it felt the same as it did two years ago.”

De Bruyne was spotted on crutches as he attended the premiere of City’s new documentary series in Manchester city centre on Wednesday night.
