Date: March 4, 2001 @ El Bernabeu
Final score: Real 2-2 Barca
Eventual La Liga winner: Real Madrid
Complex says: Hat tricks don’t come along too often in this fixture—there’s been one in the last 15 years—but bad refereeing decisions are much more common. If you’re a Brazilian player called Rivaldo and about to outscore the King of the Bernabeu, Raul (who had also scored two), to bag a hat trick and win the game for Barca in Madrid, then you might find that dubious offside calls come into play. See the clip above for Rivaldo's pair of scintillating goals, and the one that wasn't.
