Stand-in skipper Raheem Sterling scored the only goal as Manchester City returned to winning ways in their Premier League clash with Arsenal.
Sterling, given the armband by manager Pep Guardiola with Fernandinho on the bench and Kevin de Bruyne injured, finished off the rebound after Phil Foden's 23rd-minute shot had been saved.
Arsenal had chances to level but City keeper Ederson denied them with three excellent first-half saves and both David Luiz and Pepe were off target with free-kicks in good positions after the break.
The result extended a miserable run of away results against their fellow 'top six' members for Arsenal.
