Benfica and Argentina midfielder Pablo year contract extension Thursday through the 2012-13 season.

Aimar, 32, joined Benfica from Spain's Real Zaragoza in 2008 and has played 85 league matches and scored 12 goals.

"I'm very proud that they want me for another year," said Aimar, according to the UEFA website. "It wasn't difficult to reach an agreement as both parties wanted this. It's another highlight of my career and my life."

Aimar played 52 matches for Argentina from 1999-2009, and has also played at River Plate and Valencia during his career.

Benfica is unbeaten after 17 games, and leads the Portuguese Liga standings by five points over FC Porto.
