Even though the first leg ended in a goalless draw, but i consider that result a s good as a victory. Barcelona has been very strong in their home matches and should win this match by at least a couple of goals. Last time when Villarreal visited Camp Nou they were thrashed 4-0. Ronaldinho didn't have a great game then, but scored one of the best goal of last season. Ronaldinho is back in the side along with Rafael Marquez. For me returning of Marquez is the most important as it gives more stability in defense. We can expect Ronaldinho to get some time on the pitch in the second half. It’s very important not to start with him as it will only add to his voes this season. Gudjonsen is out so we can expect Iniesta and Xavi to start in the middle. Bojan looks to me the best bet at the centre and should do well with Messi and Henry.
In the defense Rijkaard might stick to the tried and tested with Zambrotta and Abidal making up the Full Backs. Milito and Puyol are expected to guard the Goal in front of Valdez. I believe we will win by a couple of goals. May be a Copa Del Rey trophy is the one which will inspire the team to reach unconquered heights.
