Star footballer Lionel Messi has been forced to back down in his attempt to leave his lifelong football club FC Barcelona. The Argentine ended weeks of speculation by announcing he'd reluctantly decided to stay for one more season. Messi said he would see out his contract until next year to avoid taking the club to court. The player wanted to leave on a free transfer - but Barca and the Spanish league say he's bound by a $837 million buyout clause.
