However, Hilton has warned suitors about Neymar's mentality.
"If he really leaves the French league, it will be a shame, we do not know what's going on in the head of a football player, there have been a lot of problems since he was in Paris and I think he wants to go somewhere else," he told L'Equipe.
"His injuries prevented him from showing everything that is worth. He is a fantastic player, he is undisputed, but we talked a lot about his little problems outside the field and his private life, which was what prevented Neymar from being really good in Ligue 1, even though he was one of the best players in recent seasons.
"He lacks that (leadership), it's obvious, he has talent but not enough strength in his head to be a leader on the field."
