I think the problem why never have success forward on Barcelona right now because depending with midfielder position
If you look closely at the current problem in Barcelona squad, it is quite complex and not in the midfield line only. They have no strong strikers, less creative midfielders, and weak defenders. I can understand if the quality of Barcelona squad is decreasing because most of the players are still young and have less experiece. While the old players in the squad aren't in their top performance anymore. The solution should be signing top players who fit with Barcelona game style. Unfortunately, Barcelona has no money to sign them since they have a serious financial problem. Even, Barcelona management plans to put the players who have a big value and salary on the transfer list. They try to decrease their financial burden.
I think midfielder is the key for team playing what have to do when attacking and defensive moment, if midfielder can't manage the game style will be broken and hard for forward how to scoring goal on every match. I know Barcelona problem in this season most complicated except goal keeper only. Defender is need new player position and Pique should out because he was over and very late when against team make attacking counter and he left several step from against forward. Barcelona need defender have good speed and most hardest how Ramos playing and Pique character is not enough good I think.
Yes, actually the problem is in the whole Barcelona squad because the squad is just not strong enough, and also the chemistry between players is not top quality, to be honest.
And we are also thinking that because we are used to seeing Barcelona playing with the world's best players and providing the results which are absolutely beyond belief but now to be precise they have lost it all.
Now they don't have any good players and don't have the money to buy players too. They have to somehow finish in the top four and save some money to buy better players probably in the next season which will be in the best interest for Barcelona.
