Former France coach Raymond Domenech believes Lyon should sell Corentin Tolisso.
Domenech believes Tolisso should be sold to make way for Lucas Tousart.
"This is a real headache, especially for Bruno (Genesio), who has a culture of young players and coaching," Domenech told L'Equipe.
"Lucas passes after the others, but he proved he was able to do at least as well as they did. When you have a player like him, you can let Tolisso go."
Tolisso is a target for Juventus, while he has conceded hopes of playing for Arsenal.
"Many clubs make me dream like Real Madrid, FC Barcelona and England with teams like Arsenal," he said.
"I like the Premier League and I think I am well suited to it. It is the league that offers the most competition, it is the most open, the most hard-fought and the most spectacular."
