Lyon are ready to offer a new deal with an annual salary of at least four million euros ($4.5m, 2.9m pounds) to star striker Alexandre Lacazette in an attempt to keep him at the club.

"Alexandre wishes to be the number one and receive the biggest salary at the club, which is absolutely understandable. He will earn at least four million euros a year," said Lyon president Jean-Michel Aulas on Friday at the site of the club's new stadium, which is due to open early in 2016.

Lacazette has become a target for leading clubs around Europe after ending last season as the top scorer in Ligue 1 with 27 goals, but Aulas said it would be "a strategical error" to sell the French international.

"That is why we have made him an offer that will see him become the best paid player at Lyon by far," added Aulas.

Lacazette, France's player of the year, is currently under contract until 2018 and Aulas said that he would be consulted, along with club captain Maxime Gonalons, about potential new signings.
