Pep Guardiola admitted he feared Ilkay Gundogan had suffered another serious injury as the midfielder punched the turf in pain but said initial reports are that the problem is 'not serious'.
Gundogan was starting a match for the first time since rupturing his anterior cruciate ligament last December when he was forced off following a foul by Claudio Yacob in the Carabao Cup tie at West Bromwich Albion.
The Manchester City player walked gingerly from the field flexing his left knee – he previously damaged his right – but Guardiola was pleased that the diagnosis was positive.
