The likes of Carlo Ancelotti, Unai Emery, Thomas Tuchel and Mauricio Pochettino all failed to deliver that elusive Champions League trophy to Paris Saint Germain.
Christophe Galtier is the new man charged with trying to deliver that elusive Champions League crown at the biggest club of his managerial career to date.

So far, Galtier has enjoyed spells at five different clubs, one on an interim basis, all based in France.
Starting with his interim role at Marseille, a club where he enjoyed two spells as a player, the former defender went on to have managerial stints at Bastia, Saint-Etienne, Lille and most recently at Nice.
Galtier's most successful spell came during his time at Lille between 2017 and 2021, where he managed to guide Les Dogues to their first Ligue 1 title in 10 years.
Beating big-spenders PSG to the title in 2020/21, to deliver Lille’s fourth ever top flight title was a remarkable achievement, yet, two days after winning the league Galtier walked away from the club.
Many expected Galtier to move on to a bigger club but instead he made the somewhat surprising move to Nice, where he helped Les Aiglons finish fifth last season and finish runners-up in the Coupe de France.
Leaving Nice last month, Galtier has finally taken that big step up in club standing and now finds himself at the biggest team in France and a regular contender for the Champions League crown.
PSG are the current third favourites to win the Champions League next season at 11/2, with Manchester City at 11/4 and Liverpool at 9/2.
One of the first high-profile issues Galtier has been forced to address on his arrival at the Parc des Princes is the future of forward Neymar.
The ongoing Neymar saga has rumbled on almost since his arrival in the French capital from Barcelona back in 2017.
Links with a return to Barcelona have surrounded the 30-year-old over the past couple of years, and once again Neymar is being linked with a move away from Paris this summer.
Clubs in the Premier League, Spain and the USA have all been linked with moves for the talented forward.
Galtier is a big admirer of the Brazil international and has made his stance very clear on the former Santos starlet.
Speaking on the topic of Neymar's future Galtier told reporters: "What coach wouldn't want him in their team?
"I have a clear idea of what I want from him. I hope he stays because it is better to have him with us than against us."
Galtier will be eager to keep the front three of Neymar, Kylian Mbappe and Lionel Messi together for at least one more season, as the trio look to finally secure European glory for the Parisian giants.
Mbappe’s future was sorted before Galtier’s arrival after turning down what was an expected move to Real Madrid, while it appears Messi will be around for at least one more season.
Perhaps a new manager and some fresh ideas will be a key factor in convincing Neymar to stay at the Parc des Princes beyond the summer.
There is no doubt the PSG squad has the talent to go all the way in the Champions League but having fallen in high-pressure games in the past, Galtier will need to perform some mental healing.
PSG could do far worse than look at the side who knocked them out of the competition last season, in eventual winners Real Madrid.
Dismissed throughout last season, Real manager Ancelotti managed to build a united team and squeezed every ounce of effort out of the squad to cause major upsets and eventually beat Liverpool in the final in Paris.
On paper, it could be argued PSG have the better side than that of Los Blancos, but it was the Spanish giants who managed to go all the way.
Galtier had the ability to galvanise Lille and give them a siege mentality that helped them to defy the odds to win the Ligue 1 title.
That man management and ability to handle the pressure should stand Galtier in good stead for what will be somewhat of a media circus at PSG, where drama is never too far away.
Paris Saint-Germain has chewed up and spat out some top-quality managers in recent years and now it's time to see if Galtier can be the one to make himself a PSG legend.
