Paris Saint-Germain have confirmed they are withholding Zlatan Ibrahimovic's final bonus payment amid a dispute with their former striker.

Swedish newspaper Expressen reported on Friday that Ibrahimovic is still waiting for his final payment from PSG, with legal representatives on both sides attempting to negotiate a settlement.

PSG then informed French newspaper Le Figaro that they are waiting for a document from Ibrahimovic in order to release his money.

"The club has always respected its commitments. Forty-eight months of wages have been paid on time," the club statement said.

"We are now waiting for a document the player is contractually obliged to provide us with to release final bonus payment.

Ibrahimovic, who joined Manchester United as a free agent after his PSG contract expired in June, had told French channel SFR Sport this week that "I miss my last salary from Paris."

The comment appeared to be in jest -- or related to the fact that he took a small pay cut upon signing his one-year deal at Old Trafford -- but Expressen reported that Ibrahimovic was serious.

PSG press officer Yann Guerin said he had "no comment" on the matter when reached by Expressen, who also reported that Ibrahimovic's legal team was ready to take the matter to court if a solution could not be found.

One possible cause of the dispute could be a reported "loyalty" clause in Ibrahimovic's contract at PSG.

In June, The Telegraph reported that the striker's move to Old Trafford was being held up because of a clause that would have given him a bonus if he did not sign with another club until after his contract expired on June 30.

But on that day, Ibrahimovic revealed on social media that it was "Time to let the world know. My next destination is Manchester United."

United did not confirm the move until the next day, when Ibrahimovic officially became a free agent.

In the SFR interview, Ibrahimovic further suggested there was a rift with PSG when he responded to a question about the club's Champions League hopes by saying "It is not my problem!"
