Barca added the Copa del Rey to their La Liga triumph on Saturday with a 3-1 win over Athletic Bilbao, leaving them on course for the treble ahead of Saturday's meeting with Juventus.

"Watch and learn how to win a final. Long live Barca and long live Catalunya. And don’t forget to be in front of the TV on June 6,” read the tweet that included a photoshopped image of the Real Madrid team crouching in front of a television set.
Stoichkov, who won five Spanish titles and a Champions League during his time at Camp Nou, has made a habit of taunting Madrid.
In March he said Real Madrid should sell “Messi-obsessed” Cristiano Ronaldo, while earlier this month he suggested the club "stick to basketball”.
