BARCELONA, Spain (AFP) — Barcelona survived a huge scare from Paris Saint-Germain yesterday to qualify for the Champions League semi-finals for the sixth successive season on away goals after a 1-1 draw at Camp Nou stadium.

The 2-2 draw between the pair in last week’s quarter-final first leg had handed the advantage to the Catalans, but with star player Lionel Messi only starting the return as a substitute due to a hamstring injury, they seemed nervous throughout and PSG deservedly went in front just after half-time through Javier Pastore.

However, with Messi summoned from the bench, Pedro fired home 19 minutes from time to send Barca into the last four.

And the winger was even more relieved to have scored the equaliser, having given the ball away in the lead-up to the PSG goal.

Even without Messi, Barca came within inches of the perfect start when Xavi curled a free-kick inches past Salvatore Sirigu’s right-hand post.

Thereafter though the first period belonged to the visitors who capitalised on Barca’s uncharacteristic slackness in possession to take a stranglehold on the game, thanks in particular to the pace and drive of Lucas Moura.

The Brazilian saw a fierce strike from outside the area well handled by Victor Valdes, before he and Ezequiel Lavezzi both wastefully shot over when well-positioned.

Lavezzi then had the biggest chance of the first half as he latched onto Zlatan Ibrahimovic’s through ball, but his prodded effort lacked the power to beat Valdes who comfortably blocked with his feet.

Ibrahimovic was the provider again as Lucas saw a headed effort at the back post turned over by Valdes as the pressure from the French league leaders continued.

The goal that PSG had been threatening all night finally did arrive five minutes after the break as an excellent one-two between Pastore and Ibrahimovic sent the Argentine in behind the Barca defence and this time there was nothing Valdes could do to keep out his left-footed finish.

Pastore missed a great chance to register his second of the evening eight minutes later from another lightning PSG break, but this time he scuffed wide from 12 yards.

Dani Alves then had Barca’s best chance up to that point of the evening as he blasted over when unmarked at the back post before Messi replaced Cesc Fabregas to a huge ovation.

Messi’s arrival instantly forced Barca onto the front foot and, after Gerard Pique had a shot blocked, Iniesta forced Sirigu into his first serious save with Messi unable to control the rebound.

Pastore dragged another shot wide at the other end as PSG maintained a threat on the break, but the Parisians were made to rue their wastefulness in front of goal as Barca equalised on 71 minutes.

Inevitably, Messi was involved as he jinked past a couple of defenders and rolled the ball into David Villa who laid it back for Pedro to smash home.

And despite a nervy final 15 minutes for the hosts, PSG couldn’t create another clear opening as Barca join Real Madrid, Borussia Dortmund and Bayern Munich in tomorrow’s semi-final draw.

In Turin, Italy, Garemany’s Bayern Munich continued their march toward a second consecutive Champions League final with a 2-0 win at Juventus yesterday, securing a 4-0 win on aggregate and a place in the semi-finals.

Mario Mandzukic all but killed off the tie in the 64th minute, heading in a rebound to leave Juventus needing to score four goals in 26 minutes.

Claudio Pizarro added Bayern’s second in stoppage time, while Arjen Robben hit the post for the German champions.
