The Spaniard is currently on loan at Deportivo La Coruna after being deemed surplus to requirements at the Emirates.
The La Liga club are expected to try and sign the 29-year-old permanently next summer when his loan expires and an offer of around £13m could get a deal done.
But, according to Le 10 Sport, Marseille are keeping tabs on Perez too and could join the bidding.
The French club are said to be scouting the striker during his loan at Deportivo and they may move for him next summer.
Perez has quickly settled into life at his old club and he got his first goal of the season last month against Getafe.
