Roma chief Monchi will not rule out selling goalkeeper Alisson Becker.

Alisson is being linked with Real Madrid, Liverpool and Chelsea.

"There's no such thing anywhere in the world as an unsellable player," Monchi said of the Brazil No1.

"The perfect answer would be to say that he's unsellable, but I can't say that because such a player doesn't exist.

"If someone came in with €500m (£440m) for Pastore, maybe he would leave. There is no team in the world that can talk about unsellable players."
