Lyon coach Bruno Genesio says they won't block Alexandre Lacazette should he wish to leave.

Arsenal saw a bid in the region of £30m rejected last week but are expected to return with an improved offer for the 25-year-old.

"He can leave if Lyon want him to," said the 49-year-old.

"There are some offers that you cannot refuse. My desire as manager is that the best players stay and Lacazette is very important for the team.

"I have been assured by my president that we will keep the player. You never know what could happen right up until August 31."
