The striker dedicated his side's third and crucial goal to his relatives as he won Europe's premier club competition in his first season with the Catalan side
"It is the reward for all work and we are very happy to have achieved this in a stadium as important as this. It was a very important title for the club and now it's ours." Villa told TVE shortly after the final whistle.
"If you know us, you know that we never relax. We have ambition, we have potential and very hungry for titles. We could not waste this opportunity."
Villa acknowledged that his strike came at an important juncture of the match, as Manchester United went in search of a second equaliser following Lionel Messi's second goal.
"My goal came at a good time and gave us piece of mind. We went 3-1 up and it decided the match. We are very happy having achieved all of this.
"I dedicate it to all my family, my daughters and also Pepe Reina's, who are like my nieces.
Villa had come into the final having scored just one goal in his previous 15 appearances (against Osasuna).
