Barcelona won the final 2-0, after goals by Samuel Eto’o and Lionel Messi.
“We didn’t come here and give a good account of ourselves,” Ferdinand told Sky Sports News.
“We have played better 99 per cent of the time this season, but saying that we created four or five good opportunities to score, but they scored two goals at crucial times and two bad goals on our part.
“But we have no arguments, they were the better team on the day, you have got to do it on the day – if we played better or played to our strengths it would have been a different game, but if you don’t do it on the day you don’t deserve to win.”
Vidic added: “We didn’t play well.
“They had a good game and scored at the right time – then we chased the game and they had space to counter attack us, they deserved to win.”
