Olympique Lyon president Jean-Michel Aulas insists Alexandre Lacazette will not leave on the cheap this summer.
Lacazette refused to pledge his commitment to Lyon at the club's awards night this week.
But Aulas insists: "For Lacazette, he is priceless. 50 million, it will not be enough for him.
"There is no discussion with PSG about Lacazette."
L'Equipe reports 'half of Europe' are chasing the centre-forward for the summer market, including Arsenal and Liverpool.
