They thought that by bringing Neymar in they would have all they needed to win the Champions League title. They didn't, and the fans then started blaming him. Before he went to PSG he was part of one of the most productive and iconic attacking trio in history: Messi, Suarez, and Neymar. Messi and Suarez wanted to support Neymar’s career. He was loved at Barcelona. PSG was/is a mercenary club, and when they didn't win Champions League the ownership and fans soured on him.
True words.
You cannot win championships at the highest level with a team full of egomaniacs with little ambition since they have all the money they’ll ever need.
Even bringing in Mauricio Pochettino, who is probably one of the best team builders out there couldn’t hack it.
