Manchester City are fearing an extended absence for Benjamin Mendy with a knee injury.

Mendy featured in five of City's eight victories. Pep Guardiola could use Danilo on the left but he preferred Fabian Delph in Tuesday's Champions League match. City could also operate a wingback system featuring Leroy Sane or Raheem Sterling.

Mendy will fly to Barcelona to see specialist doctor Ramon Cugat on Thursday.

City bought Mendy for £52 million this summer.
