The football world thrives on unpredictability, and nowhere is this more evident than in the Spanish Super Cup.
While giants like Real Madrid and Barcelona often dominate the headlines, this competition has a hidden history of massive shocks.
Fans love seeing an underdog rise to the occasion and humble the titans of La Liga.
From stunning aggregate scores to legendary individual performances, these upsets remain etched in the memories of supporters worldwide.
The Night San Mamés Stunned the World
In 2015, Athletic Bilbao delivered perhaps the most shocking performance in the modern era of the Spanish Super Cup.
Facing a prime Barcelona side led by Lionel Messi, the Basque underdogs secured a historic 4-0 win in the first leg.
Aritz Aduriz became an overnight hero by scoring a sensational hat-trick that left Luis Enrique’s team speechless.

This result wasn’t just a fluke; Bilbao held their nerve in the second leg at the Camp Nou to finish with a 5-1 aggregate victory.
It remains a definitive moment in the tournament’s history, proving that even the best can fall.
Mallorca’s Historic Triumph Over the Galácticos
Back in 2003, Mallorca proved that stars don’t always win trophies in the Spanish Super Cup.
Despite Real Madrid fielding a “Galácticos” lineup featuring Zidane, Ronaldo, and David Beckham, Mallorca secured a 2-1 win in the first leg.
Samuel Eto’o, playing against his former club, was the catalyst for this unexpected defiance.
While Madrid eventually recovered in the return leg, the initial shock sent ripples through Spanish football.
