Emiliano Viviano, co-owned by Inter and Bologna, says he will only leave for Real Madrid.
The two Serie A sides share a co-ownership in Viviano, who has become Italy's first choice goalkeeper in the absence of Gianluigi Buffon.
Viviano sees his future in Serie A, but said resisting an offer from the Spanish giants would be hard.
"I am well here, but I also know that turning down certain offers would be difficult," he told Il Corriere dello Sport.
"I will only leave for Real Madrid, but I do want to stay here longer. However, I will decide my future with Bologna and Inter."
