France striker Kylian Mbappe joins PSG on loan from Monaco

Manchester United's Paul Pogba watches on as Les Bleus were put through their paces

Friday's announcement from European football's governing body said it would look at whether PSG had violated the regulations, which are created to prevent football clubs spending more than they earn.

And while Neymar's signing was the biggest fee for 2017, do you know the players involved in the most expensive transfers of each of the past 20 years?

But the Uefa committee has taken the unusual step of investigating in order to support the credibility of the FFP rules and monitor how PSG account for their mammoth spending.

Its board will meet regularly over the coming months to evaluate all documentation relating to the case.

PSG were previously punished under FFP rules in May 2014 when the Qatari owned club's sponsorship agreement with the Qatari Tourism Authority was deemed to have an unfair value by UEFA's independent investigation panel.

"UEFA considers Financial Fair Play to be a crucial governance mechanism which aims to ensure the financial sustainability of European Club Football".

Number of Ligue 1 goals he netted last season, together with six in as many Champions League knock-out games.

The French club said they were "very confident" that they are in full compliance, insisting that they "always operated in total transparency" and have the "upmost respect" for UEFA.

The striker was 17 years and 62 days old when he scored his first Ligue 1 goal, helping his side to beat Troyes in February 2016, making him the club's youngest goalscorer - again displacing Henry.

PSG triggered Neymar's €222m buyout clause to acquire him from Barcelona on August 3, and sealed Mbappe's before Thursday's deadline on an initial loan in a deal that sources said is worth €180m plus bonuses.

No financial terms of the deal were disclosed, but European media reported that PSG would pay up to €180m (NZ$299m) for Mbappe, just short of the club's deal with Neymar, who joined PSG from Barcelona for €222m (NZ$354m).

"It's vital for French football to keep and to help progress such a talent in our league", PSG president Nasser Al-Khelaifi said.

PSG's stunning 222 million euros capture of Neymar from Barcelona earlier this month has sent transfer fees skyrocketing across the continent. "The worldwide French striker is transferred on a loan basis from AS Monaco until June 30 2018", PSG said in a statement.

That is already being born out in increased revenue through merchandising, in particular, with PSG shirts being sold out.

Among the sanctions risked by PSG if they are found to have broken those rules is a ban from the Champions League.
