Olympique Lyon coach Bruno Genesio is eager not to lose Alexandre Lacazette.
The subject of two bids from West Ham, Lacazette has also been linked with Arsenal and Tottenham.
But Genesio says: "The players that I want to keep? Tolisso and Lacazette, to mention only the main players approached by the outside.
"I am confident of my chairman and if he wants to keep these players, they will remain at OL. The club does not need to sell. Now the decision is taken by the player last.
"If the player has a stronger desire to go to a club, we will not refuse, we will open the discussions."
