Barcelona midfielder Sergio Busquets has signed a contract extension to keep him at the Camp Nou until 2015.
Busquets, 22, put pen to paper his new deal on Thursday morning at the club's offices, alongside president Sandro Rosell.
The new agreement contains an automatic extension for a further year depending on games played in the 2014-15 campaign - and a buyout clause from €80 to €150 million.
Busquets made his senior debut during the 2008-09 season and has since established himself as an important member of Pep Guardiola's squad.
After penning the new deal, Busquets told Barca TV: "I'm happy. It's the best way to start the year - great news for everyone. I am very young, I'm 22 years old, and hopefully will have a career full of successes.''
He said he felt "joy, excitement ... many sensations - all positive" at having committed his future to "the best club in the world".
A club statement confirmed: "Barca midfielder Sergio Busquets this morning signed a contract extension that will keep him at the club until 2015.
"The deal also includes the chance to extend the contract based on games played in its final season. The buyout clause [has been] upped from €80 to €150 million."
