Barcelona are suing former player Neymar for 8.5m euros (£7.8m) over his world record move to Paris St-Germain.
The 25-year-old Brazil forward who made the 222m euro (£200m) move to the French club in August after buying out his contract is expected to return the renewal bonus he was paid nine months ago when he signed a new five year deal, 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.”
Paris St-Germain later responded to say they were “surprised” by Barcelona’s statement, adding: “The club repeats that, along with Neymar Jr, it strictly respected all applicable laws and rules and can only regret, once again, the attitude of FC Barcelona.”
The lawsuit was submitted on 11 August to the Labour Tribunal in Barcelona.
The BBC Sport reported that “Following the transfer, Barcelona announced the club was withholding a further 26m euro (£23m) loyalty bonus from the player”.
