Buffon could move to Porto to replace Iker Casilla, who is weighing up retirement after his end of season heart attack.
“The idea of playing for Porto interests Gigi," agent Silvio Martina told O Jogo.
“However, there isn't a serious offer on the table and we haven't met anyone yet.
“He would be open to making the move. After all, we're talking about a club with a great history, who play in the Champions League."
