It was supposed to be Argentina against France, and Lionel Scaloni said as much before kick-off. But by the time the 2022 World Cup final reached its breathless conclusion at Lusail Iconic Stadium, the night had bent itself into the purest possible duel: Lionel Messi versus Kylian Mbappe. Four years later, the footage still has a strange pull, especially one clip that supporters claim shows Mbappe getting one over his then Paris Saint-Germain teammate.

The two PSG stars produced five of the six goals in a final that felt less like a football match and more like two prize fighters refusing to leave the ring. Messi opened the scoring with a composed penalty, then Mbappe flipped the script with a last-gasp brace—a spot-kick and a stunning volley—to force extra time. Messi thought he had settled it when he scrambled home from close range, only for Mbappe to bury another penalty and drag the contest to a shoot-out.

Naturally, a clash of that size made fans wonder whether the cordial dressing-room relationship between Messi and Mbappe could survive the tension. They were teammates at the Parc des Princes, but on that night they were rivals fighting for immortality. And if some social media detectives are to be believed, the rivalry spilled into a very pointed gesture.

The clip in question shows Messi pumping his fist in the direction of Mbappe, apparently after an Argentina goal. Mbappe can be seen glancing over his shoulder, as if checking whether the celebration was aimed at him. It is hard to imagine Messi deliberately poking the bear, but the edit then shows Mbappe making the exact same gesture after scoring for France while Messi is just feet away and looking in his direction before the restart.

So was it revenge? Was it a coincidence? That is the sort of question the internet loves to argue about until the early hours. All's fair in love and war, as the old saying goes, and if Mbappe really was playing mind games, he picked the biggest possible stage to do it. Even if he was not, there is enough in the footage to suggest that one of them believed something more than chance was unfolding, even for a split second.

It is also not difficult to understand why Mbappe might have wanted to break free of Messi's shadow at PSG and in the wider footballing ecosystem. There were no shortage of reports at the time claiming the French star wanted to be the top dog in Paris. These days, of course, the landscape has shifted again: Messi has moved on to Inter Miami, while Mbappe eventually took his talents to Real Madrid. But in December 2022, they were still sharing a dressing room and, according to the viral clip, perhaps swapping a few pointed gestures on the biggest night of their careers.

By the end of the night, only one of them was left fist-pumping with a gold trophy in his hands. Argentina triumphed on penalties, Messi completed the final missing chapter of his international story, and Mbappe walked away with a hat-trick and a silver medal. Yet the clip endures, because it captures something football fans cannot resist: two all-time greats circling each other with a mix of respect, rivalry, and just enough ambiguity to keep the debate alive.

With the 2026 World Cup now looming on the horizon, the football world may be gearing up for another chapter in this rivalry. But the 2022 final remains the reference point—a night when a team sport briefly became a one-on-one blockbuster, and a small fist-pump turned into a lasting piece of football folklore.
