There was a lovely moment at the end of the game in Munich where the already-subbed Dembele could be seen wildly celebrating a team-mate winning a tackle close to the touchline. It's not something one would have expected to see from the Frenchman even a couple of years ago.
Before his second-season explosion at Parc des Princes, Dembele was rightly regarded as one of the game's great unfulfilled talents. He even admitted himself that he wasted five years at Barcelona. But he took on board everything Luis Enrique tried to teach him at PSG - and now he's looking to win the Ballon d'Or and Champions League for a second consecutive season.
His good friend and former team-mate, Kylian Mbappe, has yet to win either - and he's no closer to doing so two years after leaving the French capital in pursuit of both prizes. In fact, Mbappe’s career is now moving in a very worrying direction.
Admittedly, the France forward has scored freely since arriving at Real Madrid in 2024 but he's yet to win a major honour with Los Blancos. PSG, by complete contrast, are one win away from becoming the first team to retain the Champions League trophy since Cristiano Ronaldo's Real.
It's not a good look at all for Mbappe. He may be one of the most valuable players on the planet, but his worth is now being openly questioned in the Madrid press - along with his character and commitment.
In the same week that the injured attacker stands accused of caring only about himself by going on holiday during a trying time for his club, PSG's players are being universally praised for a newfound sense of unity - as perhaps best exemplified by Dembele.
So, while eyebrows were raised when Luis Enrique claimed that the Parisians would become a better team without Mbappe, he's long since been proven right. PSG have grown stronger since he left, while Madrid have got weaker.
