But that could all be set to change, with Luis Campos set to become their new director of football.
Campos has frequently been labelled as one of the best talent spotters, with his transfers helping Monaco reach the Champions League semi-final and Lille win Ligue 1.
But before he became renowned as a transfer guru, Campos started off as a coach in Portugal.
He became boss of Leiria at just 27 years old, before going on to coach various amateur clubs, which led to him getting the job at Portuguese top-flight side Gil Vicente.
His teams were renowned for playing good football, and his Gil Vicente side made the headlines for ending Jose Mourinho's unbeaten 27-game start to the season with Porto in April 2004.
Despite initially being divisional rivals, they eventually became close allies, which saw Mourinho bring him to Real Madrid in 2012 to become a scout and data analyst.
Even though he had just landed himself a job at the Spanish giants, an approach from newly-rich AS Monaco to become their director of football would see him begin his career as a talent finder for Europe's biggest clubs.
In his first summer at the club, the club were one of the biggest spenders in Europe, spending roughly £140 million, including a club-record £50m for Radamel Falcao and £40m for James Rodriguez.
However, spending big wasn't necessary for Campos to secure top talent.
He signed Bernando Silva, Tiemoue Bakayoko, Fabinho, Thomas Lemar and Benjamin Mendy for £43m - all of whom played in Monaco's route to the Champions League semi-finals in 2017.
He then sold them for a combined £231m, yielding a £188m. That's how you master the transfer market.
That's without including the £162m he made from Kylian Mbappe, who he helped bring through at Monaco and has led to the two having a very good relationship.
He then went to Lille and pulled off similar miracles, signing the players that helped beat PSG to the Ligue 1 title in 2020/21.
Despite a slow start on the pitch, he made £130m profit from Nicolas Pepe, Rafael Leao, and Victor Osimhen.
That funded moves for the likes of title-winners Zeki Celik, Renato Sanches, Jonathan Ikone, just to name a few, who were bought for a combined £25m. They could now be sold for around four times that.
So it makes sense as to why PSG have bought him in.
Signing players to make a profit won't necessarily be the modus operandi. The French champions have enough money to not have to worry about that.
But it'll be about signing the right players to help them finally win the Champions League.
One of those signings has already been made and it could be the most crucial of tenure - Mbappe's new contract.
It's unclear whether Mbappe signed because he knew Campos was coming in, or Campos managed to persuade him to stay himself, but their good relationship will have had an impact.
And Campos' connections could come in handy again, with his pal Mourinho reportedly a 'strong contender' for the PSG job.
"Mourinho is like a brother to me," Campos once told Sky Sports.
"I know him very well and for a long time. He's a wonderful person and the best coach in the world."
Another of Campos' former colleagues, Christophe Galtier, who he worked with when Lille one the league, is also reportedly a contender for the job.
Whoever is manager, it's probably safe to say that PSG are finally in good hands with Campos at the helm.
