Zinedine Zidane’s men required a penalty shootout to get the better of Atletico Madrid in Milan, with Cristiano Ronaldo scoring the winning spot-kick.
But one Barcelona fan who was sitting near Perez couldn’t resist a little dig about who are the better team in Europe.
“Florentino, you have to recognise that Barca are the best,” said the supporter.
But the Madrid president replied: “[Barca] have five. We have 11!”
The Barcelona fan retorted with: “But they are from a ‘no good’ era.”
Perez ended the debate by signalling Madrid’s 11 European Cups with his fingers and saying: ““As of now, we have 11.”
