A defeat that puts PSG's future at risk after spending one billion euros Champions League UEFA's Financial Fair Play threatens the French side

Sporting failure and economic waste are the two feelings conjured up by Paris Saint-Germain's last-16 exit to Real Madrid in the Champions League on Tuesday night, with the threat of Financial Fair Play (FFP) lingering after having spent one billion euros since Nasser Al-Khelaifi took over at the club.

Madrid's squad cost 330m euros less than that of PSG and coach Unai Emery will almost certainly pay for the defeat with his dismissal.

The total cost of the PSG squad is 805m euros and, after defying all of the financial controls set by UEFA, Al-Khelaifi has not found a way to succeed in Europe, proving that simply spending millions upon millions does not guarantee success on the biggest stage.

Taking the example of Roman Abramovich with Chelsea, the club who bought everything, it took nine years for him to win the Champions League and Al-Khelaifi has been in charge of PSG now for seven years.

The European elimination, in addition to being considered a failure after investing one billion euros in the club since 2011, puts into question the economic situation of the club as UEFA will surely look to sanction the French club.

Names like Kylian Mbappe, Angel Di Maria, Edinson Cavani, Neymar, Marco Verratti, Marquinhos, Thiago Silva, Javier Pastore, Julian Draxler, Dani Alves and so on have not sufficed for PSG to compete in the latter stages of the Champions League, showing that success cannot always be bought.

In the coming days it is expected that UEFA will claim that PSG are open to suspicion for breaking FFP rules and in the first analysis presented, they were made aware that they needed to trim the squad with Lucas Moura leaving, but that is not enough.

With their premature exit in Europe, PSG will not receive the larger stakes that are available for those in the latter stages of the competition and will instead come under the scrutiny of UEFA.

The financing of PSG will once again be looked at as it is difficult to prove whether the funds come from impeccable management, or whether they are using funds that emanate from the oil wells in Qatar.
