Sergio Busquets apologized to Barcelona supporters following their 4-0 collapse to Liverpool that knocked the side out of the Champions League semifinals. 

Busquets admitted that Liverpool were the better side. 

"They have been better than us. I apologise. After what happened in Rome, this happened again. It's tough to go out like this after the first-leg result. Liverpool have been smarter than us, they were faster. I think we had chances to score the goal we needed, but it wasn't meant to be today."
