Olympique Marseille coach Eric Gerets admits they may cash in on attacking midfielder Samir Nasri this summer.

French sources say Arsenal have already registered their interest with l'OM for the 21 year-old and are ready to open talks over a fee for the youngster.

Nasri recently signed a new deal with Marseille, which are seeking at least £12 million for the midfielder.

"Before thinking about bringing in reinforcements over the summer we need to know who is going to stay, and above all the players I want to keep," Gerets told L'Equipe.

"If there is a big offer for Samir, then of course he will leave.

"I can't criticize the club because it is the same everywhere. When there is a huge offer made, players leave."
