Barcelona has huge problems due to large financial debts, poor organization of the club, disturbed relations between players and management, incompetent management etc.
Messi's departure was logical and expected due to all these problems.
Barcelona needs a good striker? Maybe Suarez?

In fact, Barcelona now urgently needs a lot of money to save itself from financial ruin and going into football mediocrity.
They can forget about some great football successes and trophies in the next few years.
It's obvious that Barcelona is not the favorite in the Champions League this year and they are still not sure that they will pass the group stage of this competition.
This is what bothers me with the situation Barcelona is going through, they had one of the best players and one of the best runs we have ever seen and yet they are in financial issues, where all that money went? How they could get in such financial issues on the first place? After all even if there are many true fans that will keep supporting the team there are many fans that will switch to other teams if Barcelona does not improve and do so soon, and this could make their money issues even bigger than what they are right now.
