By 7pm on Saturday Spain could be crowning champions that aren't either Barcelona or Real Madrid for the first time in a decade.
Valencia were the last team to break the duopoly of those sides, but it is Atletico Madrid, without of title of their own since the 1995/96 campaign, who are threatening to break it again.
Diego Simeone's side need a draw at the Nou Camp to win the title, but Barcelona will retain their crown if they win at their home ground owing to what will be a better head-to-head record.
That the outcome of the season has boiled down to the final match owes much to the two teams' faltering finishes to the campaign. Atletico drew and lost their previous two games while Barcelona picked up just a point from their final two matches.
Heading into the game there is little to tell between the two sides - they've played five times already but only one of those has resulted in a winner - the Champions League quarter-final second leg won by this year's European finalists Atletico.
KICK-OFF: Saturday, 5pm BST
