There is a thread that connects the three leading favourites to win the World Cup starting in Qatar on Sunday.
Brazil, Argentina and holders France have been cited as the main contenders for good reason, not least because of the identity of their star players.
The trio of Messi, Neymar and Mbappe have been united at Paris Saint-Germain by the wealth of the French club's Qatari owners. Their relationship has dominated headlines in France this season, and their performances have been outstanding.
Qatar created shockwaves in December 2010 when it won the right to host this year's World Cup. A little over six months later, Qatar Sports Investments bought PSG.
Fast forward a decade and they have been transformed from an ailing club into a major force.
Mbappe and Neymar became the two most expensive signings in football history when they moved to PSG in 2017.
Messi joined them in Paris last year following his departure from Barcelona.
The World Cup has been cited as a reason for their superb form, in particular in the case of Messi and Neymar.
At 35, Messi knows he is unlikely to get another chance to win it. "It's my last World Cup, surely," he told ESPN Argentina recently. At 30, Neymar might have at least one more World Cup in him after this one, even if he has previously hinted that this could be his last.
Injury ruined the 2014 World Cup for him before Brazil lost to Belgium in the quarter-finals in 2018.
Since then injuries have hampered him in Paris. Until this season, when he has appeared fitter and sharper than ever. In stark contrast to his two club colleagues, Mbappe has already won the World Cup and was still a teenager when he did so with France in 2018.
It is he who represents the future, which is why PSG splashed huge sums to persuade him to sign a new deal at the end of last season rather than join Real Madrid.
Le Parisien recently reported that Paris would be paying Mbappe 630 million euros ($652m) before tax over the duration of the three-year contract he signed in May.
PSG dismissed that report as "sensationalist", but the figures mentioned highlight Mbappe's status.
