Who will be in the finals?

In the semi-finals of the Champions League Manchester United has a narrow lead on the youthful Arsenal, while the unstoppable Barcelona has hit a snag in their game against Chelsea. Thanks to an early goal from John O'Shea in the 17th minute and the great mixture of talent Manchester United has, Arsenal had only response and that was their goalkeeper Manuel Almunia that only saw one ball get past him. In the other game, Barcelona had to try to make a goal against Chelsea in Camp Nou (Barcelona's home). It would have been easy for Barcelona, if Chelsea hadn't put so many player's to defend. This was a bad game for Barcelona as one of their best defender's Rafael Marquez was taken out of the game in the 50th minute. Marquez will be out for the rest of the season. To me it seems it will be Manchester vs. Barcelona in the finals.
