Watching brief – Lionel Messi started the evening on the bench after picking up a hamstring injury during last week's first leg in Paris. The four-time World Player of the Year missed the weekend's win over Mallorca and was deemed fit enough to be named as a substitute.
Becks appeal – David Beckham had to make do with a place on the substitutes bench for Paris Saint-Germain. The former Real Madrid man had hoped to earn a start against his old club's great rival.
French resistance – Andres Iniesta is surrounded by PSG defenders during a frantic first half at Camp Nou. Both teams pushed forward in a contest played at rapid pace.
Zlatan's back – Former Barcelona striker Zlatan Ibrahimovic, now in the colors of PSG, proved a constant menace in the first half. The Swede, who scored in the first leg, gave the home defense plenty to think about.
Perfect Pastore – After wasting a whole host of chances in the first half, PSG finally made the breakthrough when Javier Pastore fired home five minutes after the interval. The Argentina international ran onto Ibrahimovic's through ball before beating Barcelona keeper Victor Valdes.
Pedro power – Within nine minutes of Messi's introduction, Barcelona moved level when Pedro fired a rasping effort into the corner following a lovely, intricate move. That strike made it 1-1 on the night, 3-3 on aggregate and put the home side back in front on away goals.
Star quality – Messi's 62nd minute introduction ultimately made the difference, while Beckham was left to reflect on what might have been following his team's exit from the competition.
Bayern cruise – Bayern Munich's Mario Mandzukic and Juventus' Giorgio Chiellini challenge for the ball during the second leg of the Champions League quarterfinal tie. Bayern won the opening contest 2-0 last week and arrived in Italy just days after winning the German title.
Super Mario – Mandzukic killed off any hopes of a Juventus comeback by heading from close-range with 64 minutes on the clock.
End game – Claudio Pizarro wrapped up a 2-0 win for Bayern in the last minute to seal a 4-0 aggregate victory and make it two German teams in the last four. Bayern joins Borussia Dortmund, which defeated Malaga Tuesday.
