The move ends the Uruguayan forward's three-year spell at Anfield.
Nunez joined Liverpool from Benfica in 2022 and made an immediate impact, scoring on his competitive debut in the FA Community Shield against Manchester City, a match the Reds won to lift the trophy.
Over his time with the club, the 25-year-old made 143 appearances and scored 40 goals, helping Liverpool secure both the Premier League and Carabao Cup titles.
His first campaign in 2022-23 saw him net 15 goals in 42 appearances across all competitions, earning the Player of the Month award twice.
The following season, he scored 18 goals, including a memorable late double as a substitute against Newcastle United in a dramatic comeback victory.
Nunez's final term at Anfield, the 2024-25 season, ended on a high as he played his part in securing the Premier League title for Liverpool.
His combination of pace, power, and clinical finishing made him a constant threat in attack, while his work rate and determination won admiration from supporters.
