Alexis Mac Allister has completed the medical tests as new Liverpool player and is reportedly set to sign a long term deal with the Reds, which will be valid until June 2028 – a £55m move from Brighton.
The 24-year-old Argentine also helped his country win the World Cup in December.
Liverpool need to add to their midfield with James Milner, Naby Keita and Alex Oxlade-Chamberlain leaving this summer. They were priced out of a move for Borussia Dortmund’s England teenager Jude Bellingham, who is a target for Real Madrid.
Mac Allister played a prominent part as Brighton secured European football for the first time in their 122-year history.
He made 40 appearances and scored 12 goals for the club.
Brighton manager Roberto de Zerbi last month said Mac Allister was a “great player” who deserved to “play at a higher level”.
Mac Allister joined Brighton from Argentinos Juniors in January 2019 and immediately went back to the Buenos Aires club on loan.
He played his first match for the Seagulls in a goalless draw against Wolverhampton Wanderers in March 2020 and has since made 112 appearances for the club, scoring 20 goals.
Mac Allister has been capped 16 times by Argentina and played in six games of their 2022 World Cup-winning campaign in Qatar, scoring in a 2-0 win against Poland in the group stages.
