The Brazilian ace left Los Blaugranas for a world-record fee last summer, but apparently that's not enough for PSG's star.

Neymar's relationship with Barcelona didn't end in the best of terms, and it seems that the Brazilian will make every effort to make it clear.

According to Spanish newspaper El Mundo, PSG's star has filed another lawsuit against his former team for unpaid bonuses. Neymar's lawyers believe that Neymar should be paid €30M (around $37M) over a contract extension bonus he didn't receive while playing for the Catalan giants, plus interests.

On the other side of the table, Barcelona's attorneys believe that it should be Neymar who should pay the team the portion of the bonus he did receive, plus a a fee of €8.5M (around $10.6M) for terminating his contract to join Les Parisiens for a world-record fee. If the legal system of Catalunya decides that Neymar did breach his contract, he would have to pay Barcelona €75M (some $93.5M).

The legal battle between Neymar and his former employers has been taking shape since August, when Los Blaugranas failed to pay that bonus to Neymar, since they had been alerted of the player's intentions to join PSG.
