Real Madrid and their supporters will be finding it difficult to forget Zinedine Zidane, even more so after the loss against Atletico. In the Zidane era they won every final they reached.
The Real Madrid side lost the match by a score of four goals to two, and that should be cause for concern for Zidane's replacement, Julen Lopetegui.
With the Frenchman in charge, 'Los Blancos' never conceded more than three goals in a single match. Real's defensive weakness has been exposed in Lopetegui's first competitive game in charge.
In two and a half years Real Madrid fans never saw their side concede four goals. During his time at the Bernabeu, many talked about the defensive issues at Real because his side struggled to keep clean sheets.
But, in one night, Lopetegui fared worse than Zidane - something that could cause immediate worry in Madrid. It's not only about getting off to a good start, with players who are still coming back into fitness, but the fans will be hoping they don't see more of this in the coming months.
