Messi was outstanding in the victory, which many are already declaring a classic Barca performance.
"We had to lift our heads (after Hercules) and we did. We won well, we really wanted to because the other day we did not do so well and we did move the ball quickly," said the Argentine.
"Now though we cannot afford any more setbacks in the league."
Dani Alves also talked up the team's play: "It was the best version of Barca. After the defeat against Hercules there were a lot of rumours, but maybe we've grown accustomed to people talking poorly of us."
