Too late to give predictions, but i predict a dificult win at Camp Nou, over 2 legs its pretty hard to get past Atleti, Visca Barça...
They have an incredible coach and team spirit, Barça has their Messiah, gonna be an incredible game again...

9th minute: Neymar scoring from an extremely difficult angle. Suarez picks up assist.

This is what happens when u dont park the bus

15th minute: Atletico committed 6 fouls, Barcelona only 1

18th minute: Neymar perhaps wrongly called offside in a play where he scored a goal.

Meanwhile Torres has put 3 shots on target since coming back to Atletico, and has scored from all 3 of those shots.

21st minute: Jordi Alba helplessly play-acting after linesman's flag falls on his head.

30th minute: Raul Garcia scores from a penalty. Mascherano given yellow card. Contact was made on Juanfran a few centimeters outside the box, but as per the rule, if the player falls inside the box a penalty can be awarded (same as Messi vs. Demichelis in FCB 2-0 MC).

35th minute: Referee calls Suarez on a dive which appears to be a very controversial call. Jimenez's challenge was hip-to-hip, but the strength of the challenge is what is to be disputed. Suarez fell in a heap.

38th minute: 2-2. Busquets' header off a corner hits off Miranda for an own goal. We're all even at the Calderon.

41st minute: 3-2, Neymar again! Messi crosses in to Alba, who knocks it back for Neymar to tap in. Controversy: Just seconds before, Griezmann slams a shot into Jordi Alba's hand, which looks to be a clear penalty and red.

There is no rule of falling inside the box, Messi vs di michelis was a wrong call, not a penalty but straight red.
( Anyway in that game 2 goals unfairly refused for Barça for inexistent offsides )

Blessed to have those players, because those refrees mistakes could have send Barça out of competition, Neymar goal was valid and the penalty was clearly outside of the box...

Penalty refused for Atleti for a handball but they already been given one for free...

Red card: Gabi sent off at half-time for an unknown incidence. Atletico playing with 10 men.

Arda Turan just attempted to throw his boot at the linesman. Fortunately, it missed.

The entire stadium has, literally, turned their back to the match. The supporters are all facing the outside of the stadium in protest of Gabi's red card.

Messi never dives, massive respect.

84' Second yellow and a red for Mario suarez, pathetic tackle on messi

You can't expect to perform against Barcelona with 9 men...

The awkward moment was when Madrid lost to atleti, the whole world went on and on by "passion >money" and when we say they played dirty, they thought of us a sore losers, but now after barca won, they understand that atleti play rough...

Turan throwing a boot at the linesman summed up the entire match for me. Not to mention that Atletico were too dependent on the referee. They were too busy calling Alba's handball to realize that Messi had launched a counter-attack, and didn't get back on time to defend.

People who say Atleti don't play dirty football have NEVER and I STRONGLY emphasize on NEVER, have watched Atleti play. They are just as dirty as Simeone was when he was a player!
