FC Barcelona have sued Brazilian Neymar over his move to to Paris St-Germain.
The 25-year old joined PSG in a world record fee of 222m euro (£200m) after PSG accepted to trigger his release clause.
Neymar, who has been exceptional in his first two games for the Paris club are on the radar of Barcelona once again as this time as they are claiming breach of contract over a bonus payment triggered when Neymar signed a new five-year contract with them in October 2016.
The Catalans are seeking to receive “8.5m euros (£7.8m) in damages, and an additional 10% in interest”.
The club released a statement saying; “The club demands the player return the already paid sum as he has not completed his contract”.
The statement continued: “The club also requests Paris St-Germain take on responsibility for the payment of these fees if the player cannot do so himself”.
The lawsuit according to the club was submitted on 11 August to the Labour Tribunal in Barcelona.
Following the transfer, Barcelona announced the club was withholding a further 26m euro (£23m) loyalty bonus from the player.
Neymar on Sunday criticized the directors of the club after scoring twice on his home debut for PSG in a 6-2 win over Toulouse.
“I spent four beautiful years there and parted happy,” said the 25-year-old. “But with [the board], no”.
“For me, they are not the people who should be there, for the direction of Barca. Barca deserve much better”.
