Brazilian centre-back Lucio has signed a two-year contract extension tying him down to Inter Milan until 2014, the club confirmed on Wednesday.
The 33-year-old joined the Italian giants from Bayern Munich on a three-year deal in 2009, winning a treble of trophies in his first season under Jose Mourinho.
The former Leverkusen defender had 12 more months to run on his old deal but has now signed on for an extra two years.
He struck up a formidable central defensive pairing with Argentina's Walter Samuel in his first season although the latter's injury woes last season saw Lucio paired with Andrea Ranocchia.
Lucio, a World Cup winner in 2002, has been capped 104 times by Brazil.
