Ahead of that fateful Reims match, Mbappe had made it clear for some time that he needed to play alongside a central striker, rather than be the focal point himself. The Frenchman felt that having a big presence up front would allow him to dart in behind, and make clever runs around the pitch - a modern, modified version of the old-fashioned big man-little man system.
And in some ways, Mbappe had a point. He has repeatedly been at his best in a France shirt when paired with Olivier Giroud, the big striker serving as a focal point around which Mbappe thrives.
In the summer of 2022, it seemed that his wish to have a similar player to work with at PSG might come true. Mbappe had signed a massive new contract to stay in Paris, and it was clear that he expected a No.9 to arrive in the aftermath. But the Parisian hierarchy didn't provide him with one. Football advisor Luis Campos reportedly looked into signing Benfica's Goncalo Ramos, but the deal never materialised. And while promising Rennes striker Hugo Ekitike was signed, but never cracked the XI.
So while Mbappe, Lionel Messi and Neymar still made for a fearsome front three, it forced the former to play a role he didn't feel he was best suited to. He made that clear during the September international break of 2022, highlighting the differences between playing for PSG and the national team:
"I play differently [with France]," he said. "I am asked other things here compared to with my club. I have a lot more freedom here. The coach knows that there is a number 9 like Olivier who occupies the defences and I can walk around and go into space. In Paris, it's different, there isn't that. I am asked to do the pivot, it is different."
Galtier refused to get dragged into a media feud, and instead placated his disgruntled star. "His analysis is fair," Galtier admitted. "He isn’t in the same configuration here as he is with the French national team. It is a conversation I had with him during the pre-season and one that I also had with the president and Luis Campos."
Still, the damage had been done. Mbappe was scoring goals, but he wasn't happy. The Parisians responded by overcompensating last summer, bringing in two natural No.9s in Ramos and Randal Kolo Muani. Mbappe, as a result, is averaging over a goal per game, and even though Luis Enrique has fiddled with his XIs - and sometimes uses Mbappe in a central role - the France forward had a point when it came to how he fit in under Galtier.
