PSG made the biggest transfer of the summer when they brought in Neymar for £200 million, on a five-year deal.
President Nasser Al-Khelaifi was questioned about the move in relation to FFP at the time, but insisted he was not worried about the situation.
PSG then further added to their ranks by bringing in Kylian Mbappe from Monaco, initially on loan, but with an option to buy, with the deal set to cost up to £165.7 million.
