Barcelona midfielder Sergio Busquets admits they froze on the night as Liverpool pulled off a famous Champions League shock.

Defending a 3-0 lead, Barca lost 4-0 at Anfield as Liverpool reached a second consecutive final.

"They were better than us, they went all out to win the game from the start and we really struggled with their pressure especially at the start of both halves," a despondent Busquets said.

"I can't say anything else, all I can do is say sorry to our supporters because, after last year in Rome, to go out like this after such a good result in the first leg is very tough, there's little else to say.

"Once they scored and they pressed us high it was very difficult. I think we had the chance to score the goal that we needed but it wasn't to be," the midfielder said.

"When you face a team like this which presses you very high up the pitch and you don't make the most of second balls they just keep pushing further forward and with this atmosphere it was very difficult."
