Lionel Messi wants to remain at Barcelona for as long as the club can satisfy his hunger for trophies.
Barcelona captain Messi is in his 16th season as a first-team player at Camp Nou, having made his LaLiga debut in October 2004.
The 32-year-old signed a fresh four-year contract in 2017 but the agreement has been revealed to include a clause which gives him the option of leaving on a free transfer at the end of each campaign.
Messi, who denied being in talks over a new deal, does not intend to leave, although his commitment comes with one key condition.
"What I can say is that I want to be at Barcelona as long as possible," Messi said in an interview with SPORT.
"I've said throughout my career that this is my home. But I also don't want to have a long-term contract and only be here because of it. I want to be here because physically I'm fine to play and be an important member of the squad. And as I said before, I need to see there's a winning team because I want to keep winning things at this club."
"For me, money or a clause don't mean anything. Other things motivate me and the most important thing is having a winning team."
He added: "Obviously, I want to win and I want to win at this club. This is my home. I don't have any intention of going anywhere but I want to keep competing and winning."
At the top of his wish list is a fifth Champions League crown.
Messi and Barca looked set to end a four-year European drought upon reaching the semi-finals last season, only to give up a three-goal first-leg advantage as they crumbled to defeat against Liverpool at Anfield.
