Barcelona performance was great when they beat Atletico Bilbao and surprisingly they could win with a big score, this victory of course can be a good start for Barcelona especially when they must play in the champions league, although their chances of qualifying are very small but I think Barcelona should be able to continue play optimally and hope that luck will be on their side later, I think the defeat from of Madrid has become a whip for barcelona to quickly rise and be able to compete again with Madrid who are ranked at the top standings.
Of all the teams in La Liga, only Real Madrid have not been able to beat Barcelona this season even though they drew once against Rayo Vellecano, but Rayo Vellecano is not a very strong team in La Liga. And I'm sure that Barcelona can beat him in other games this season as well.
Just to beat Real Madrid, I'm still a little hesitant because Real Madrid's quality is still above average when compared to other teams in La Liga. But I also hope for Barcelona's revival this season so that when Barcelona meet Real Madrid again in La Liga, I hope the game can be even more exciting than before.
