Leo Messi scored twice after a feisty encounter which saw numerous clashes between the sides.
Xavi said: “We put in a good performance and it’s a fair result. This is a victory for football.
“We got the result that we deserved. We were again superior.
“We’re a team that wants to play attacking football and have fun on the pitch.
“They [Real Madrid] are just hoping that we’ll make mistakes. That worked in the Copa del Rey final, but not this time.”
