Spain is geared up for a dramatic final day of the season in a 'winner takes it all' situation as Barcelona host Atletico Madrid in the title decider.
Heading into today's game, Atletico sit top of La Liga by three points from today's opponents Barcelona, but the Catalan giants have a vastly superior goal difference, meaning a win for Gerardo Martino's men will clinch the title.
It's somewhat surprising that they could be just 90 minutes away from winning the league once again having been criticised so much this season, and with Martino and a number of players seemingly poised to exit the club this summer, a rebuild is set to take place at the Camp Nou.
They face off against Atletico, who have been simply outstanding ever since Diego Simeone took charge in late 2011. They have not only won the Europa League under his stewardship, but are also in the Champions League final - where they will meet city rivals Real - and simply need to avoid defeat to win La Liga for the first time since 1996.
The two teams have met four times this season, and Barcelona are yet to win after three draws and an Atletico win. Everything is on the line in today's meeting, on a day which promises twists and turns throughout.
