Brazil legend Claudio Taffarel believes Roma goalkeeper Alisson Becker will become the best in the world.

Alisson has been linked with Real Madrid and Liverpool.

The 25-year-old is unlikely to sign a new deal with the Serie A side and could well be on the move after this summer's World Cup.

"In the time that we worked with him at Internacional and with the national squad, we knew he would reach a high level," Taffarel told Omnisport.

"I'll always respect the career of Buffon, who has been brilliant. But I believe that Alisson, as a goalkeeper, is more technical with a different posture.

"He always stands assertively and is confident in what he does. Alisson is really impressive.

"There is more time needed to see if he can reach the top or not, but he has the qualities to stay on top and become the best goalkeeper in the world, without doubt."
