Uefa opened a “formal investigation” into Paris Saint-Germain (PSG) on Friday after the French club broke the world transfer record to sign Neymar.
The Ligue 1 giant also completed a loan deal for Kylian Mbappe, with an agreement to pay Monaco 180m euros in the summer in order to avoid breaking the Financial Fair Play (FFP) rules.
European football’s governing body said it would look at whether PSG had violated its Financial Fair Play (FFP) rules.
“The investigation will focus on the compliance of the club with the break-even requirement, particularly in light of its recent transfer activity.
“In the coming months, the Investigatory Chamber of the Uefa Club Financial Control Body will regularly meet in order to carefully evaluate all documentation pertaining to this case,” Uefa said in a statement.
“Uefa considers Financial Fair Play to be a crucial governance mechanism which aims to ensure the financial sustainability of European club football,” the statement added.
FFP
The FFP system was first approved by Uefa in 2010 to try and combat soaring debts in the game.
From 2013 to 2015 clubs could only post a net total loss of €45 million, which was reduced to 30 million for the next three years, running until 2018.
Non-compliance with the rules can result in a series of disciplinary measures, ranging from a warning to the deduction of points, and even exclusion from European competition.
PSG have already incurred sanctions for a previous violation and were slapped with a 60-million-euro fine, 40 million of which was suspended in 2014, and saw their squad for the Champions League cut from 25 to 21 players.
