Story highlights Barcelona beats Atletico Madrid 2-1

Luis Suarez double in Nou Camp

Torres scores for Atletico then sent off

Bayern Munich beats Benfica 1-0

(CNN) Luis Suarez rescued Barcelona with a second half double as the European champion beat 10-man Atletico Madrid 2-1 in their quarterfinal first leg clash in the Nou Camp Tuesday.

The Uruguayan can rarely have scored more important goals for the Catalan giant, which trailed to a 25th minute goal from Fernando Torres, who then turned from hero to villain by promptly getting himself sent off for two rash challenges.

Torres celebrates after opening the scoring but his joy soon turned to agony in the Nou Camp.

Torres is shown the red card by referee Felix Brych after a second rash challenge.

Barcelona, so lackluster in the first half and with its defense of the Champions League under real threat, finally woke up after the break, but it took until the 63rd minute to draw level.

Neymar hit the woodwork and wasted two other clear opportunities before Suarez, quiet until that point, scuffed home his effort after Jordi Alba's mishit shot found him in front of goal.

With Atletico now pinned back, Barca's second was almost inevitable and 11 minutes later it was Suarez who met a Dani Alves volleyed cross with a bullet header.
