Nicollin says Villa are currently the only bidders from the Premier League for the 23-year-old, who is set to leave the Ligue 1 outfit.
"He is leaving," Nicollin told LeSport10. "There are four or five clubs that have come in. It is now down to the player to choose now because we are almost in agreement with the clubs. He will leave for 14-15 million euros."
"We have no problem now, he [Belhanda] has the authority to agree with whoever he wants now."
