Dybala brace has Barca facing exit from Champions League
Juventus 3 Barcelona 0
Barcelona need another Nou Camp miracle if they are to reach the Champions League semi-finals after a crushing 3-0 loss to Juventus in Turin.
Paulo Dybala struck twice in a stunning first half and Giorgio Chiellini added a third after the break as the hosts claimed a commanding advantage ahead of next week's second leg.
Dismal Barcelona's only hope is to repeat their feat of the previous round, when they recovered from a 4-0 first-leg loss to Paris St Germain by beating the French side 6-1 at home.
But on the evidence of last night a second comeback looks unlikely after Juventus dominated proceedings with the help of Dybala's brilliant first-half brace.
Luis Enrique's men, smarting from a defeat to Malaga at the weekend, looked clueless over how to deal with their opponents' attacking threat and fell behind after just seven minutes.
Juan Cuadrado found Dybala on the right side and the striker curled an excellent left-foot shot into the net.
Barca responded well and could have grabbed an equaliser after 20 minutes when Lionel Messi threaded the ball to Andres Iniesta, whose low shot was well saved by Gianluigi Buffon.
Moments later, Juventus surged down the left flank and Mario Mandzukic crossed for the unmarked Dybala, who put the Italians 2-0 up.
Messi had an effort ruled out for offside on the half-hour.
Barcelona started the second half in much better fashion with Messi rolling an effort inches wide of the upright and Buffon just beating Luis Suarez to an Ivan Rakitic through-ball.
Chiellini made it 3-0 after 55 minutes, out-jumping Javier Mascherano to head home.
Barcelona began to press but the Juventus defence held out and Messi's last chance saw him hit a free-kick into the wall.
• THREE explosions around Dortmund's team bus as it made its way to the stadium in the German city resulted in the night's other tie - against Monaco - being rescheduled for tonight at 5.45pm.
Defender Marc Bartra was taken to hospital with arm and hand injuries.
