Barcelona: Lionel Messi, Luis Suarez and other questions

With Barca seemingly in disarray, there are some key questions facing the Catalan giants as they attempt to dispel the theory they are a fast-fading force.

It's impossible an analysis of Barca's plight with any subject other than Lionel Messi, following the captain's aborted attempt to leave and his subsequent outbursts against unpopular president Josep Maria Bartomeu.

Messi made it clear on Friday that he is still very unhappy with the club, making a scathing point in his farewell message to departing team-mate Luis Suarez, who has joined Atletico Madrid.

"You deserved a farewell fitting who you are: one of the most important players in the history of the club. Not to be kicked out like you were. But the truth is by now, nothing surprises me," Messi wrote on Instagram.
