Lyon president Jean-Michel Aulas says the club is treating Friday like the final day of the transfer window amid links between star midfielder Houssem Aouar and Arsenal.
Aouar has been linked with a big-money move all summer, having emerged as a star for the Ligue 1 side.
The 22-year-old midfielder scored nine goals in 41 games last season, earning a place in the UEFA Champions League Squad of the Season.

Aulas has claimed that Arsenal are reluctant to meet the club's valuation of Aouar, although he did admit that Gunners boss Mikel Arteta remains a big fan of the midfielder.
