I don't know why it's always a balance with teams that score too many goals, I mean their back seems to be always open and they concede alot which is not very good although it brings out the very best because it's like competition when they concede more goals but if they find the balance to have a strong defense line they would be far above most of the teams in la Liga even the giant Real Madrid.
This is a part that is very hard for many teams to resolve, it seems it is a hard thing to come about a team that has it all. Some of them will have a little and some will have more, but it is very hard to see a team have it all. Barcelona has proven so much of their talent and I think they could still be their best form despite all the hurdles they had to face during the season. This team has proven beyond reasonable doubt to be able to achieve what they wanted this season despite all the big hurdles they need to face, they were able to conquer them all. They can do better next season and concede less goals than they did this season.
