He took his momentum to slide on the soggy lawn of the Parc des Princes and celebrate in his usual way his first penalty in the Champions League with Paris.
As in the first leg, where he scored a hat-trick at Camp Nou, Kylian Mbappé scored against Barcelona.
And, as often, this achievement makes him go down in history.
He becomes indeed the youngest player in history to reach 25 goals in the Champions League, at 22 years and 80 days, doing better than a certain Lionel Messi (22 years and 286 days).
The statistics duel he delivers from a distance with Haaland is therefore far from over.
In the absence of Neymar, the Parisian striker did not miss, with this successful penalty, his new European meeting.
Four days later, a still convincing performance in Brest - with a double - Mbappé was nevertheless expected this Wednesday.
Before the meeting, questioned at the microphone of the club's TV and broadcast on the giant screens of the Park, Bernard Lama, the former Parisian goalkeeper, had slipped: "What is difficult for him is that each time we have him. request to repeat performances as on the go.
But that's also what he expects of himself: to repeat this kind of matches.
"
Little success in the game
But for the rest, Bondy's child has disappointed.
He actually tried as soon as he was served, often by Verratti, to embark on the large-scale actions he is so fond of.
But he was not really successful in the game. We saw him annoyed when his center, after his breakthrough, found no one (16th).
Ter Stegen is lying on his strikes (17th, 42nd).
For the rest of his evening, Mbappé nevertheless suffered.
First by the fault of Oscar Mingueza who, after giving him a blow in the face, tackled him from behind a few seconds later, passing not far from a double warning (26th).

And it was on the ground, then from the sidelines, still holding his head, that he saw Navas push back Messi's penalty.

He finished the match without more success, like this strike far above after a splendid breakthrough (90th).
Between now and the quarter-final first leg, on April 6 or 7, it remains to be seen whether he will say more about his future.
Jérôme Rothen, the former Parisian, wanted it in our columns this Wednesday.
"If I have one message for him it's:
Kylian, be clearer,
" Rothen said.
The soap opera is far from over.
