Jabarkan Benfica dari Pablo Aimar dalam bahasa melayu

On 17 July 2008, after a period of intense negotiations, Aimar signed a four-year contract with Portuguese side Benfica for a fee of €6.5 million. After a difficult first half of the season, he managed to overcome his constant injuries and finished it in good shape.

In 2009–10 Aimar was in better physical conditions, and displayed a good offensive chemistry with countryman Javier Saviola, newly signed, as Benfica had the best offensive record of the competition, with the help of top scorer Óscar Cardozo, winning the club's 32nd championship, after a five-year wait. He played 46 games in the following season all competitions comprised and scored seven goals, but the Reds only conquered the domestic League Cup.

On 6 June 2013, after 179 official appearances and 17 goals, 33-year-old Aimar announced he was leaving Benfica, thanking the club for "five wonderful years".
