The coach of the Catalan side was in no doubt that his team earned their victory, which he felt was the result of having plenty of time in which to prepare for the showpiece event
"It is never easy. We must congratulate Manchester United for the great match they have played. We are pleased because we know how hard it is to win the Champions League," he told TVE.
"We prepared very well for this game and the world has seen that we deserved to win. We controlled the game superbly."
Guardiola hailed his side's preparation ahead of the encounter as key to their success but even in victory, he praised Manchester United for cancelling out Pedro's opening goal.
"This year we had more time to prepare for the final compared to the one in Rome. We were able to prepare well for it and we had a great game. We are very happy with the victory.
"The history of Manchester United told us that we would have a hard time. They played at a high level and managed to equalise so soon after we scored the first goal. I think we must be happy because we were very competitive today."
Guardiola has now won the Champions League twice in three seasons since taking over from Frank Rijkaard in the summer of 2008, with Barcelona also lifting the trophy under Johan Cruyff in 1992 and Rijkaard in 2006.
