Their are (not counting Messi and CR7 because as they age out it gets tricky to call it, and in 2, 3 years max they are so done as WC top 5 players anyway)
only 4 dominant players on the planet atm
Mbappe
Håland
De Bruyne (he can keep it up, level wise until he is 33, 34 or so I think)
Lewandowski, but he has only a year or 2 peak left, max, after this season, he already turns 33 this coming summer (he got FUCKED out of the Ballon d'Or by those rotters not awarding it even though the season was basically completely in most all things)
imagine all of the first 3 at Citeh, lol, under Pep
Neymar is sorta close, but is SO injury prone and turns 30yo in less than a year, and I expect a large drop off once he hits 32 or so
