Goalkeeper Iker Casillas has made several great lunging saves as Real Madrid has weathered a late offensive charge from Barcelona at Camp Nou in the second leg of the Champions League semi-finals.

Real Madrid didn't get a shot on goal, as Barcelona dominated most of the action in a scoreless half.

Barcelona had several chances to scores, but were either denied by Casillas or were just off the mark.

As expected, Barcelona has dominated time of possession, 75% to 25%. Real Madrid already have 13 fouls in the match, compared to Barcelona with four. Real Madrid defender Ricardo Carvalho picked up a yellow card.

Real Madrid doesn't seem to be playing with the urgency of a team that is down two away goals on aggregate. Cristiano Ronaldo has yet to make his presence felt, and there has been little pressure on Victor Valdes.

It took added time for Real Madrid to pick up their first corner kick.

The two main questions going into the second half are how much longer can Casillas keep Real Madrid in the match, and when will Real Madrid make a real effort to score?
