Lyon president Jean-Michel Aulas is hoping to drive up the price for Houssem Aouar.
After their Champions League elimination, Aouar is expected to be sold by Aulas this summer.
Arsenal have already had an offer of cash-plus-Matteo Guendouzi turned dowm by Aulas as rival suitors make their interest known.
Manchester City and Juventus are also in contact and Aulas is eager to see an auction develop.
So much so, reports L'Equipe, that OL's president is adjusting his valuation for Aouar from €40m to a hoped for €60m this summer.
