The former Porto playmaker says he would have to consider any offers that were made.
"Arsenal? It's a great club who we [Marseille[ have already played twice in this season's Champions League," he told Mais Futebol.
"I feel I will continue at Marseille because I have signed a contract here, but it all depends on the offers and Marseille's interest.
"If there is a good club that comes in for me then what will happen remains to be seen."
