Saturday Night Fever - Spanish La Liga final matches

The Spanish media are describing it as Saturday night fever. Any one of the top 3 teams could win, although Sevilla are counting on both Real and Barca losing while they themselves win.
Real and Barca are level on points, 2 ahead of Sevilla. Real are top due to better head-to-head record against Barca. Goal difference doesn't count.
I hope Real Madrid win, as Barca scored a 'hand of god' goal in their 2-2 draw with Espanyol yesterday. Plus, Beckham has been great for real.
