Luis Cesar Souto de Moura says there are continuous inquiries for the highly rated striker, but no club has yet cemented its interest with a formal offer.
Tottenham had reopened talks with the Brasileirao side at the start of June regarding its long-term transfer target, but De Moura insists that no deal is imminent, and he is hopeful that the sought-after striker will remain at the club.
"Nothing has come in. Clubs from everywhere sound him out all the time, but we don't even consider that anymore, as there are too many inquiries but offers never come," Moura told Esporte Interativo. "I am working with the idea of keeping the player, so that he doesn't leave."
The Brazil international has played 16 times for his country and was the top scorer at the Olympics last year, but he had to pull out of the Confederations Cup due to injury.
