Lionel Messi exposed his outrageous talent against Real Madrid and scored twice to beat Mourinho's team 0-2. With this result, Guardiola's team is virtually qualified for the Champions League final, even when they still have to play the second game.
As we know, Manchester United defeated Schalke with a stunning 0-2 as visitors. After this games, it's very likely to have a Manchester United vs. Barcelona in Wembley.
Only a miracle would help Real Madrid beat their classic rival with a three goal advantage. And Mourinho already said that it will be "impossible". Ferguson knows that Messi will be his next rival.
