"Is Leandro Damiao on the market? Well, in life everything has its price," Internacional President Giovanni Luigi told the Corriere dello Sport.
"We received an offer from Napoli, it's true, but not directly. Damiao's manager Vinicius Prates told us they are prepared to invest 18m.
"However, that is not enough and we do not intend to give discounts. Our player is worth 25m, not a penny less, and if Napoli want him then he's going to cost 25m. We're here and ready to talk."
