Manchester City are rocked by news that Kevin De Bruyne could be out for another month.

The Citizens had just got De Bruyne back, after he recovered from an early season knee injury.

But now it appears that he has hurt himself again, in the Carabao Cup win against Fulham.

Goal.com reports that it will be at least four weeks that De Bruyne is out of action.

He will travel to Barcelona to receive treatment and will miss the Manchester Derby next weekend.
