Since the inauguration of Campus PSG, the French capital club's youth sports project - supported by major players such as Nasser Al-Khelaifi, Luis Campos and Yohan Cabaye - has taken on a whole new dimension.
Here, excellence is no longer an option but a norm: PSG want to reap the rewards of a new synergy between the pros and the academy, after becoming the second youngest team to lift the Champions League.
It was against this backdrop that the 'Espoirs' group was born a year ago. Replacing the former reserve team, this structure bridges the gap between the youth training centre and the elite squad.
The press, including Flashscore's French desk, were able to take a close look at the new structure over the course of an entire morning on Thursday, in an atmosphere that was both serene and studious.
As a reminder, PSG was singled out by UEFA after the league phase of the Champions League for the mobilisation of its communications teams, who responded to the greatest number of media requests around the matches.
And in this vein, PSG can also pride itself on being one of the few clubs in Europe to organise an open media day for their young players.
At 10 am, after a special welcome for the media present at the Campus, the players took to the pitch under the watchful eye of Jean-Francois Vulliez for an hour and a half of training.
The technician, a renowned trainer who came through the ranks at Olympique Lyonnais, is the embodiment of this desire for professionalism.
Very proactive from the outset, Vulliez has never stopped giving his voice, pushing his players to the limit.
Shared DNA with the first team
After warming up without the ball, followed by high-intensity runs, the staff introduced some fun exercises: working in groups of four with the aim of finishing in small goals to combine precision technique and muscular awakening.
Once the bodies were warmed up, it was time for the heart of the training session, which revealed the direct link with Luis Enrique's squad: a passing circuit exercise focusing on finishing and half-field opposition under the new Parisian DNA.
The keywords? Pressure and intensity. As soon as the ball is lost, the reaction has to be immediate to suffocate the opponent, just like in the senior squad.
"My greatest source of pride? Our mission remains the same: to develop the players," explained the coach in the mixed zone at the end of training.
"We do that through matches, training sessions and all the club's resources, whether video, mental, medical or nutritional.
"We put a framework in place, but then it's up to the players to do the work. We create the path, but it's up to them to walk on it. Some progress quickly, others take longer."
To conclude this morning, nothing was left to chance. In preparation for the semi-final against Real Madrid, the staff orchestrated a full penalty shootout.
It was a symbolic but important exercise, reminding us that the European dream depends on mastering every detail.
Working hard to create future stars
As was the case a year ago for the pros prior to their first European final, PSG opted for transparency and openness to give visibility to its young players. It's a strategy that is paying off for a club that is no longer content with simply buying stars, but is now working hard to create them.
And the question is this: which exercise is more complicated - training with a ball for almost two hours or going under the microscope, whether in the mixed zone or one-to-one with an accredited journalist?
"Given what's at stake this season, we see it mainly as an experiment," continues Vulliez.
"There's a lot of excitement, a lot of media coverage, and it's something they'll experience later on at the top level. Our role is to bring them along as freshly as possible, under as little pressure as possible, so that they can express their qualities."
Just as on the pitch, communication is part of the life of a professional footballer, and the demands must be the same as when you kick a ball. And Paris Saint-Germain know that.
"It's true that it's unusual, but we don't feel any particular pressure," Pierre Mounguengue explained to the press.
"We're concentrated on our work and focused on this semi-final. Our objective is clearly to make history at the club. If you want to reach the top level, you have to go through these matches.
"The Youth League is a great competition, and if you hope to break into the first team, you have to do well there."
