Internacional have confirmed the bid this week.
â€śWe received an â‚¬18m verbal offer from Napoli, according to the playerâ€™s agent,â€ť director of football Luis Cesar Souto de Moura told Lancenet.
â€śWe donâ€™t accept that this is Leandro Damiaoâ€™s value. We are certain he will play the 2014 World Cup with Brazilâ€™s national team.
â€śWe have not had any talks about setting a value as we don't intend to sell the player. The offer that was presented to us was lower than what he is worth.â€ť
