UEFA has confirmed the investigation into Paris Saint-Germain’s potential breach of financial fair play rules is to be reopened.
In June the club were cleared of breaking FFP rules, and the investigation from the footballing body was dropped.
UEFA stated on Monday it would be referring the case back to its financial unit “for further investigation”.
The investigation into the Qatari-owned club’s spending was initially opened in September 2017, under pressure from some of Europe’s biggest clubs, after the French club signed Brazilian forward Neymar for a world-record A$362million.
Within weeks the club had also agreed a deal to sign teenage striker Kylian Mbappe from Monaco, on a season-long loan with the obligation to buy for $300m.
UEFA rules mandate that clubs cannot spend more than they earn in any given season and deficits must fall within a 30-million-euro limit over three seasons.
PSG’s case is complicated by their lucrative sponsorship deals with Qatar National Bank and the Gulf state’s tourism authority.
If ultimately found guilty PSG could face exclusion from European competition for one or more seasons.
