Liverpool have signed Brazil international Alisson in a record transfer fee for a goalkeeper.
The deal for the 25-year-old is thought to be worth up to £66.8m (72.5m euros), surpassing the previous record of 53m euros paid by Juventus to Parma for Gianluigi Buffon in 2001.
Alisson has been at Roma for two years, playing 37 Serie A games in 2017-18.
He said: "In terms of my life and my career, it's a huge step for me being part of this club and this family."
