Alisson says Fabinho is both the most important player for Liverpool and Brazil.
The 27-year-old can operate at a number of positions, including holding midfield and centre-back.
And Alisson believes it is Fabinho's versatility which makes him so integral to his two teams.
"I believe that Fabinho is the most important player for both the club and the national team," said the Liverpool goalkeeper.
"He is a very important player wherever he is, he always proves his worth on the pitch.
"He had been playing for Van Dijk and, unfortunately, with his injury he has been missing for Brazil too.
"He can play as a number six, as a defender, he was a wide player in the past and these characteristics bring even more value to him."
