Ronald Koeman was only a few minutes away from landing his first trophy as Barcelona boss but saw the Supercopa snatched away when Oscar de Marcos equalized in the 90th minute and Inaki Williams then sealed the win with a stunner in extra-time.
The Dutch boss had almost been enjoying himself recently after seeing Barca go nine games unbeaten in the build-up to the match but the scrutiny will be back on the coach after another disappointing evening.
It may have only been the Super Cup but this was still a chance for Barca to pick up a trophy for the first time in 18 months and try to move on from a really dismal spell.
