They tried their best, but it was obvious from the start that the difference was huge, and that is what happened with this as well. Barcelona may looked like they were having trouble for a while, but then it turned out to be nothing big at all, and they won easily in the end no matter what happened at the start. Barcelona does look like a team that is having some trouble lately, they look like they may not be as good as they could, and that's the biggest shame in clubs. When you know you are better than what you look like, but you still end up not playing as well, that never really feels good, its like not catching up to your potential.
