Messi says

                  Trailing 2-0 from the first-leg, Messi had restored parity on aggregate with two sumptuous strikes before half-time and further goals from David Villa and Jordi Alba after the break rounded off a wonderful evening for the Catalans.We needed a night like that, not only to get through but to erase the memory of that result in Milan.Everything came off perfectly. I think our fans knew just how we were going to respond and we, the players, knew the crucial thing was to re-establish our way of playing.This is the Barca that we and our fans want to see every gameAnd the Argentine believes his first goal, after just five minutes, was the key moment.We wanted that opening goal as soon as possible to cut the deficit and to make the fans feel it was going to happen. It was lightning quick movement of the ball to get it to me and, happily, I put it away. That's why we celebrated with such joy.Barca's comeback was even more remarkable given their poor form of late.Defeat in the first-leg at the San Siro had been followed by two defeats in five days to arch rivals Real Madrid, but Messi said the players always trusted that they could find their top form when they needed it most.This is the kind of performance we've been producing for years. Perhaps in the last few matches we've lost a little of our form. We knew, however, that to go through all we really needed was to get back to being ourselves.The evening was even more special for Villa after enduring a difficult time since breaking his tibia at the Club World Cup 15 months ago.From the fifth minute when we got that important first goal, we just went after Milan in every way," he told Uefa.com
