Nah, I don't think it's about form, it's about Messi, once he's back on the pitch, they'll go back to the old Barca we all know. Without Messi, this team in form or out of form is average mainly because Valverde is a mediocre manager.
This is an underlying problem that the club management has to tackle. A club that has spent the amount of money Barcelona has on sign-ins over the past two or three seasons shouldn't be dependent on just one player (no matter how great that player is).
There are quality players, but not enough quality in the technical crew to manage them.
I agree with you. Why does a team as big as Barcelona that has a lot of funds still depend on one person? Isn't there still 10 people in the team if there isn't one of these players. What is the point of buying expensive and great players if you still hope for Messi.
