Olympique Lyon president Jean-Michel Aulas believes Alexandre Lacazette is worth around £84million.
The Lyon chief believes French striker Lacazette, who remains a firm summer target for Arsenal, should be worth a similar amount to what Atletico Madrid ace Antoine Griezmann is reportedly being valued at.
"We have rejected offers worth around €40m," Aulas told Le Progres.
"I am hearing talk about €100m for a Griezmann transfer to Real Madrid."
Manchester United and Real remain the frontrunners for Frenchman Griezmann while Lacazette is believed to be a priority transfer target for the Gunners.
