Barcelona got another win which is against Alaves this time. The final score was also quite decent to improve the morale of the players. But the weakness in defense is still clearly seen. 
I don't feel like it will ever get better than this during the rest of the season either. As long as it is enough to keep them in top four it would still be some consolation for Barcelona. I'm mentioning this because Athletic Bilbao aren't far away from top four now. It would be like a nightmare for Barcelona if they don't even manage to join the Champions League. I hope things don't come to that point.

The lapses of Barcelona defenders can vividly be noticed as I was even surprised that they didn't concede a goal against Alaves last night though Barcelona did a great job by winning the match by 1:3 but however, they still need more improvement and consistency to make sure they are comfortable at the top four positions in other to book a spot in the champions league next season.
Barcelona might not be too consistent though but they're doing well because I don't think they've falled below the top six position since the beginning of the season so that's equally to show how resilient they have been in other not to be too loosed to defeat all what Barcelona needs to bounce back now is more intelligent players to tackle more especially in the defense area because that's mostly where their errors occurs most times so if they could get a solid defense then I believe the midfielders and the strikers can get the job done by scoring goals. Athletico Bilbao might seems to be very consistent on trying to move to the top four positions but I don't think they can really make it due to the current form of all the teams in the top four positions.
