Enrique forlornly turned to Paco Alcacer from the bench as the hosts played with four forwards for the final half hour.
Juventus' performance against Barcelona took Gianluigi Buffon by surprise as the iconic goalkeeper did not expect to keep a clean sheet at Camp Nou en route to the Champions League semi-finals. The club have supported him throughout and he has shaped this team, making them winners. We tried. We had a good attitude and the players were ambitious but the ball didn't want to go in. The Blaugrana found a way to win the second leg at home 6-1 giving them a berth to the quarterfinals against Juventus. "We are desperate to go as far as we can and achieve something extraordinary".
The Barca manager had talked about making their opponents nervous, but that never happened.
Allegri added: "We haven't achieved anything yet, though". Going up against tough central defenders in Giorgio Chiellini and Leonardo Bonucci, who he got by on a couple of occasions, he will have to do it again and deliver this time for Barca to move on.
He was consoled by former teammate and fellow Brazilian Dani Alves, who now plays for Juventus.
It is 21 years since Juventus won the Champions League and they must be considered contenders.
"We have to compliment the lads for all they are doing this season", he said.
"Achieving something like that over 180 minutes against Barcelona, without ever really being under a lot of pressure from one of the two-three best teams in the world, that means Juve can now target the Champions League".
Enrique insisted that his final season in charge of Barca can still end in glory.
While disappointed, Iniesta said the focus was now on beating La Liga leaders Madrid at the Santiago Bernabeu on Sunday with title holders Barca three points adrift. "We have to get ready to compete and I am sure we will do that". They did a convincing job of it, too, restricting Luis Enrique's side to a series of half chances.
Juventus carved out a couple of chances themselves but, on a night when accuracy in front of goal was at a premium, Gonzalo Higuain and Juan Cuadrado squandered their opportunities.
