LONDON (REUTERS, AFP) - Liverpool signed Brazil's Alisson from AS Roma on Thursday (July 19) for a world-record fee for a goalkeeper.

The Serie A side said Liverpool had agreed a deal worth up to €72.5 million (S$115 million) for the 25-year-old, eclipsing the previous record of €53 million paid by Juventus for Gianluigi Buffon in 2001.

Alisson made 37 league appearances for Roma last season and helped the club reach the Champions League semi-finals, where they were knocked out by Liverpool.

He started all five games for Brazil at the World Cup in Russia where they bowed out in a quarter-final defeat by Belgium.

"The 25-year-old signed a long-term contract with the Reds after undergoing a medical and completing the formalities of his switch at Melwood today," said the Liverpool FC website.

Roma confirmed the value of the transfer for Alisson.

"AS Roma can confirm that Alisson Becker has completed his move to Liverpool, in a deal that could be worth up to 72.5 million euros," the Serie A club said on Twitter.
