I watched the game, it wasn't an offside. You can watch it here: [video=youtube;q1tDsVR-l8U]http://www.youtube.com/watch?v=q1tDsVR-l8U[/video]
I predict Draw 2-2 Ronaldo will definitely score this time around. But i love barcelona on loosing side.
Madrid can win as long they don't use Mourinho lame tactic. The reason why Inter under Mourinho won against Barca is because Italian league is fundamentally a defensive side compare to any other league. On the hand, La Liga players don't really play defense. If Madrid want to win, they need to keep the posession and don't panic. And they need to use short pass rather than long pass.
Madrid just need to play of patient, and follow the instructions Mourinho. there is still a second leg to get revenge
It's not that hard actually, all you need to do is keep the ball possession. The problem is most teams are easily panic when they're up against Barca.
