ABC reports the Chilean midfielder is claiming that he is owed ‚ā¨2.4m.
Vidal has only been paid ‚ā¨1.7m in bonuses, when he believes he is due around ‚ā¨4.1m from last year, it is reported.
Barcelona are arguing that he isn't due these bonuses that are referred to.
There's also a belief that this could be a ploy from Vidal and his representatives to try to force a transfer away from the club.
"I'm not in charge of that - that's why I have my agent, my lawyer, who takes care of the awards and stuff," Vidal told ADN.
"It seems unfair to me if money is missing, but it is an issue that is alien to what we are experiencing today."
