Giannelli Imbula says he's happy at Olympique Marseille.

The young midfielder has been watched by Chelsea, whose scout Guy Hillion has confirmed their interest.

"I am very happy in Marseille," said Imbula.

"I spent quite a difficult year of adaptation, but I think this year it's going much better.

"I still have years to go here, I hope it will get better and better."
