Liverpool have completed the transfer of Brazil goalkeeper Alisson Becker from Italian Serie A side Roma on a multi-year deal.

The 25-year-old joins the English Premier League giants after undergoing a medical and completing the formalities of his move to the Reds on Thursday.

"I'm really happy, it's a dream come true to wear such a prestigious shirt for a club of this size that is used to always winning," he told the club's official website. "In terms of my life and my career, it's a huge step for me being part of this club and this family.

"You can be certain that I'll give my all."

Alisson played in all five of Brazil's matches at the 2018 FIFA World Cup Russia™, where A Seleção were eliminated in the quarter-finals after a 2-1 defeat to Belgium.
