Turin: Paulo Dybala said his two-goal performance against Barcelona on Tuesday was the sort of night he had dreamed about since he used to play on the bumpy pitches of the Argentine second division as a slightly-built teenager.

The 23-year-old is arguably the most exciting player to have come out of Argentina since Lionel Messi and managed to upstage the five-time World Player of the Year as he led Juventus to an emphatic 3-0 win in the Champions League quarter-final first leg.

Dybala scored twice to put Juve 2-0 ahead inside 22 minutes and defender Giorgio Chiellini headed in the third early in the second half.

"I am very happy because as a child I wanted to live these moments and on Tuesday I have succeeded in that," he said. "We are all in a very positive moment with a lot of confidence and that's important to go forward and achieve our objectives."?

Having made history when they overturned a 0-4 first-leg deficit against Paris Saint-Germain in the last 16 by winning the return 6-1, Barcelona will need another stunning comeback if they are to reach the last four.

Juventus last met the Spanish giants when they lost 1-3 in the 2015 final, but here they ran Luis Enrique's men ragged and nullified the visitors' front three of Messi, Neymar and Luis Suarez.

A Sami Khedira effort in the opening minutes went well over, but it was a sign of things to come in a great opening half for the hosts that saw 23-year-old Dybala sparkle.

Juve's seventh-minute opener was a work of simplicity finished off by a Dybala master stroke.

Juan Cuadrado was the provider on the right flank, setting up Dybala who turned 12 yards out and curled a left- footed shot inside the far post, beyond the outstretched hand of goalkeeper Marc-Andre ter Stegen.

It took Barca until 21 minutes to threaten, but Gianluigi Buffon denied Andres Iniesta after he had been picked out by a superb Messi pass.

Buffon pumped his fist in defiance, and he was pumping both in celebration moments later when Dybala met Mario Mandzukic's ball in from the left to sweep a first-time shot inside Ter Stegen's near post to make it 2-0.

Although his diminutive stature, speed and trickery have sometimes led to comparisons with Messi, Dybala has made a slower start to his career.

Messi had the ball in the net on the half hour, but the goal was disallowed for an earlier infringement, and Juve finished the opening half with a flurry.

Miralem Pjanic fired Cudrado's cutback high and wide, while Higuain and Leonardo Bonucci both had Ter Stegen scrambling to save in the final minutes of the half.

Barcelona coach Luis Enrique took off French left-back Jeremy Mathieu and brought on Portuguese midfielder Andre Gomes at half-time, moving Javier Mascherano back into defence.

The visitors briefly showed promise, with Suarez firing just wide of Buffon's outstretched hand, but Juve went further ahead on 55 minutes.

Chiellini, famously bitten by Suarez when Italy played Uruguay at the 2014 World Cup, held off Mascherano at a corner to send an angled header in off the far post.

Barcelona coach Luis Enrique admitted that it would be difficult for his side to pull off another great escape.

"This time, it's more difficult to believe in a comeback," said Luis Enrique.<> "It was like reliving a nightmare... I can't get the first half out of my head."

"It's difficult to pull off another turnaround like the one against PSG, although on the other hand I also thought it was unlikely that we could lose again like we did against the French team," Luis Enrique told reporters.

"It was a very difficult first half, very similar to the one in Paris, and although we improved after half-time, the first half was full of problems. It's difficult for a coach to try and do everything right for the team and then realise that he hasn't succeeded," he added.

"I don't really want to think about it now. Tomorrow will be the time to get up again and think that we have to score three goals to level the tie and four to win it."

Juventus coach Massimiliano Allegri wanted to make sure his team did not get carried away with one of their best performances under his leadership.

"We have to put some brakes on our enthusiasm," he said. "Of course, the lads have produced a great performance, both in attack and in defence. But it's just the first step. In Barcelona, it will be different and we have to try and score a goal."
