Paris Saint-Germain are “very confident” they will be able to comply with UEFA’s Financial Fair Play rules after the governing body opened an investigation into the club.

UEFA will take a close look at the big-spending Ligue 1 side over possible breaches of FFP in the wake of their signings of Neymar and Kylian Mbappe.

But PSG say they are “surprised” by UEFA’s decision and have “always operated with total transparency”.

“The club is surprised by such a step as it has permanently kept UEFA’s Financial Fair Play teams informed of the impact of all player transactions this summer while nothing obliged it to do so,” read a statement on the PSG website.

“The club is very confident in its ability to demonstrate it will perfectly respect the Financial Fair-Play rules in accordance with the financial year 2017/18.”

Mbappe’s move to PSG has left many wondering how the Qatar-owned club can avoid sanctions from UEFA considering the investment already made on Neymar.

According to media reports, the only clause required to be met to make the club’s option to buy Mbappe an obligatory one is for PSG to stay in the top flight this season.

UEFA will have to consider whether Mbappe’s transfer fee is factored into PSG’s accounts for the current season, or whether it will carry over to the following campaign.
