France striker Alexandre Lacazette has agreed a new two-year contract with Lyon, the club's president Jean-Michel Aulas announced on Tuesday.

It ties the 23-year-old to the Ligue 1 side until 2018, with Aulas confirming that agreement had been reached after "lengthy discussions".

The striker has already scored three league goals this season and could add to his two caps for France after being called up for Thursday's friendly with Spain and Sunday's game against Serbia.

Meanwhile, talented but injury-prone playmaker Yoann Gourcuff has agreed to a pay cut although not to an extension to his existing deal, which expires next summer.

The 28-year-old, a big-money signing from Bordeaux in 2010, has been plagued by injuries in his time at the Stade de Gerland.

"It was a question of making mutual concessions that show that everyone wants the best for Olympique Lyonnais," said Aulas.

Lyon have had a difficult start to the new season, losing three of their four Ligue 1 games and being eliminated from the Europa League at the play-off stage.
