Gomis has been strongly linked with a move to Newcastle United this summer, though Marseille look as though they are now favourites after expressing an interest.
it has been suggested that Lyon would be reluctant to let Gomis join a Ligue 1 rival, but Aulas has rejected that claim, insisting that "anything is possible" if Marseille offer the right money.
"There is no anti-OM coalition," Aulas tweeted. "When OM offer the price of Bafe, anything is possible."
Gomis joined Lyon in 2009 and has scored 50 goals in 141 league appearances.
