Brazilian centre-back Lucio has signed a two-year contract extension tying him down to Inter Milan until 2014, the club said on Wednesday.
The 33-year-old joined the Italian giants from Bayern Munich on a three-year deal in 2009, winning the treble with Inter in his first season under Jose Mourinho.
He had one more year 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 last season saw Lucio paired with Andrea Ranocchia.
Lucio has made 95 appearances in all competitions for Inter in his two seasons with the club, and has amassed 104 caps for Brazil in his career.
