Stephane Mbia is keeping his options open at Olympique Marseille.
L'Equipe says Arsenal, Bayern Munich, Manchester United and the Russian champion Rubin Kazan are all interested in the hard-working midfielder.
Mbia's contract carries a £14 million buyout clause and he has spoken in the past of United and Arsenal wanting to sign him.
L'OM coach Didier Deschamps would be reluctant to lose the midfielder, though after winning the French title last season, Mbia is now considering a new challenge in his career.
