There was no party for new Arsenal signing Thomas Partey as he played seven minutes for his new side in their one nil loss to Manchester City.
The 45 million pound deadline day signing from Athletico Madrid came on as an 83rd minute substitute for Granit Xhaka.
After returning from International duty with Ghana, Partey only had a handful of training sessions with his new teammates and it was no surprise he was left on the bench and did not start the game.
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.
The result extended a miserable run of away results against their fellow 'top six' members for Arsenal. They have now failed to win in their last 29 such meetings, since a success at City in 2015.
Thomas Partey was shown a yellow card late on in the game for a foul.
Guardiola is yet to drop a point against the Gunners in five encounters at Etihad Stadium since he succeeded Manuel Pellegrini as City manager in 2016.
