People throw around the word "generational talent" far too easily. A "generational talent" comes around once every 10-15 years. These players are not only exceptional from the get go but borderline world class.

Mbappé is the ONLY generational attacking talent we have right now. https://twitter.com/marinovpeixoto/status/1309988955132174338

That's not to say João isn't great. He's extremely good. I'd put him up there as La Liga's best talent but he still has much he has to improve. He's still learning and has some way to go to be regarded amongst the best in the world. He'll get there eventually.

The attacker who comes closest to flirting with the term "generational" is probably Håland. But we've still to see sustained production over a longer period of time.

In defense, Trent Alexander-Arnold is probably in that world class bracket & already has 2 fantastic seasons under his belt. I'd say he's close to being generational. No fullback is quite capable of playing such a high level at his age.
