Gomis came off the bench after a month out with hamstring trouble to head home the late winner at the Emirates Stadium and keep alive Swansea’s chances of qualifying for the Europa League.
Swansea manager Garry Monk admits he has “several players with niggles” in his squad and will wait until the final training session on Saturday before deciding on his team selection, but Jazz Richards could replace Angel Rangel (hamstring) at right-back.
Manchester City captain Vincent Kompany and midfielder Yaya Toure are both back in contention to start at Swansea in the Barclays Premier League on Sunday.
The pair were on the bench for last week’s 6-0 demolition of QPR after injury lay-offs but only Toure saw any action.
City have no fresh injury concerns but playmaker Samir Nasri is unavailable having been ruled out for the rest of the season with a groin injury.
