Athletico Paranaense coach Cuca admits Bento will be sold this summer.
The Brazil goalkeeper is being linked with Italian champions Inter Milan.
Cuca said: "Unfortunately or fortunately, we will soon lose Bento.
"He asked to leave the club, that's what all the players are looking for: We are already preparing Leo Linck (Brazilian goalkeeper born in 2001). He wants to earn a place in Europe and play in the main championships in the world."
Inter are aiming to do business with Athletico for 20m.
