Jordi Roura says there are no limits to what the "majestic" Lionel Messi can achieve after his first-half brace set Barcelona on the way to a thumping 4-0 win over AC Milan that secured the Catalans' safe passage to the last eight
Messi hit his 52nd and 53rd goals of the season inside the opening 40 minutes at the Nou Camp as Barca wasted no time in wiping out Milan's 2-0 lead from the first leg in Italy.
David Villa put Roura's men in front in the tie for the first time with a third goal after the break, but Barca remained only a goal away from elimination and needed Jordi Alba's late strike to finally set the seal on the victory.
Assistant coach Roura, again in charge of Barcelona with Tito Vilanova undergoing cancer treatment, revelled in a "special" occasion for the Nou Camp faithful, but was in no doubt about who deserved the lion's share of the credit.
"Leo gave us a majestic lesson in what it means to play football," Roura said.
"He's an extraordinary player and when he's surrounded by the best he has no limits."
Reflecting on the recent run that saw Barca lose twice to Real Madrid in the wake of the first-leg defeat in Milan, Roura added: "The players were overly criticised and they showed that they are special.
"They played with intensity, commitment and that should make us proud. I'm very pleased.
"We had a very clear idea of how we needed to play. At the break we were right where we wanted to be, level on aggregate. I told the players to be calm.
"Frankly it was pretty difficult when we were up 3-0 and it seemed as though Milan could have scored from any play.
"We controlled the tempo of the match and with the 4-0 it was over.
"We're going through to the next round because we kept a clean sheet."
Roura had further good news for Barcelona's fans after the match when he indicated that Vilanova could return in time for next month's quarter-final tie.
