Sir Alex Ferguson admitted his side lost to the better side as Barcelona won the Champions League final 2-0 in Rome, but vowed to come back even stronger.
United were bright in the initial exchanges but after Samuel Eto'o opened the scoring after 10 minutes, there was only one team in the game as Barca over-ran their opponents in midfield.
Lionel Messi made it 2-0 after 70 minutes and the Red Devils could muster nothing in response.
Ferguson said: ''In fairness we were beaten by the best team. We weren't at our best.
''The first goal was a killer, it was a bad start to the game. If you give them the ball they will keep it all night.
''But the best part of the game is that in adversity you always move forward quicker.
''We're all disappointed but we're a young team.''
