Barcelona host Atletico Madrid on Saturday as a dramatic Spanish title race concludes with a final-day showdown between the top two.
Atletico lead defending champions Barca by three points after 37 games, with Real Madrid already out of the La Liga title race.
Here's what can happen at the Nou Camp:
Barca win = Barca win the title
If teams are level on points in the Spanish top-flight then they are separated by their head-to-head record, not goal difference.
Barcelona will move level with Atletico on 89 points if they secure victory.
And it means they will go above Atletico as a win gives them a superior head-to head record, after the sides drew 0-0 in January's reverse fixture.
History is in the Catalan club's favour, having won their last six La Liga games against Atletico at the Nou Camp.
|If Barcelona win|
Draw = Atletico win the title
With Diego Simeone's side holding a three-point advantage, they know a draw will be enough to clinch a first La Liga title since 1996.
|If the teams draw|
Atletico win = Atletico win the title
Los Rojiblancos have not won a league match at the Nou Camp since February 2006, when Fernando Torres scored twice in a 3-1 win.
They know that ending this dismal record is not essential, but victory in front of a passionate Catalan crowd would end a superb season in style.
