The team that has won the Cup more times
Barcelona won their Copa del Rey number 28 tonight after beating Sevilla in the final. That's five cups more than the second team: Athletic Club with 23.
First one against Sevilla
It has been the first time that Barcelona and Sevilla faced each other in a Copa del Rey final. Both teams played each other in other finals, like last year's European Supercup, where Barcelona won 5-4 with a late goal by Pedro in the extra time (5-4)
The Kind of Cups just needs another one to become even more royal. There's one team that has played more finals in this competition than Barcelona: Real Madrid (39). However, Los Blancos have only won 19 of their finals.
