Barcelona is absolutely running through Bilbao's defense. They have already scored 4 goals without conceding even 1. I don't think there is any way Barcelona is going to lose this match. 70 minutes have been played so far. But the three goals that already have been scored were in the first 22 minutes of the match. This match is almost as good as over.
Now I think Barcelona should prepare for the next match against Bayern Munich in the champions league. That is going to be a really hard one for Barcelona since they have already lost against Bayern Munich once.
3 goals in a span of 10 minutes clearly made the Bilbao players stunned and couldn't play very well because Barcelona's breakthrough at the beginning of the first half clearly made them panic, especially in defense.
On the other hand, Barcelona are comfortable and can play freely after winning big in the first half.
They really played without a burden and of course this could be a good capital to face Bayern in a few days.
