The agent of AZ Alkmaar striker Moussa Dembele is aware of the interest of Chelsea.

Both Chelsea and Wigan Athletic have been linked with the Belgium international this week.

And his agent, Patrick Vervoort, told Foot Mercato: "For the moment, there is nothing concrete. I know that Chelsea last summer followed him.

"Regarding the €20 million, I think that price is too high, especially when you look at market conditions (laughs). If he goes it will be next summer because of his contract (which expires in 2011).

"At this time, the club should do something. Moussa wants a new level."
