UEFA orders 'further investigation' of PSG over financial fair play
European football's governing body initially opened an investigation into the Qatari-owned club's spending in September 2017 under pressure from some of Europe's biggest clubs after the French club signed Brazilian midfielder Neymar for a world-record 222 million euros (USD 261 million).
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 its lucrative sponsorship deals with Qatar National Bank and the Gulf state's tourism authority.
If eventually found guilty PSG could face exclusion from European competition for one or more seasons, a huge blow to the club's Qatari owners who have made winning the Champions League their key goal.
