Neymar has angered the Barca board after labeling president Josep Maria Bartomeu a "joke" this week. He's also spoken critically of the current regime.
However, Diario Gol says, via backchannels, Neymar has been warned to wind his neck in.

Bartomeu has taken the action, fed up with the constant goading from the Brazilian.
