The Frenchman, who is currently with his national team at the World Cup, is widely regarded as one of the best young attackers in European football.
A terrific 2013-14 campaign for Sociedad has intensified the interest in the 23-year-old, but he has hinted that he could remain with the Basque club.
"We'll see. Hopefully I can stay. I'm going to wait," he told ESPN Mexico.
A host of Premier League clubs have been linked with the attacker.
