Sorry but I don't buy that. If Neymar was born in England and played in the PL, he wouldn't have any reason to leave and play in two different countries. As it happens, Neymar comes from a Brazilian backwater league so has to move to Europe. Now personally I think his move to PSG was entirely financial and not for sporting reasons. As if Neymar grew up dreaming of winning the French league.
What has teenage girls going crazy about Neymar got to do with Kane being better or not better than Neymar. That is simply down to marketing.
Kane would never go to a crap league like France. To me it shows a lack of ambition. Neymar went there for the money and nothing else. He may believe they can win the CL but PSG aren't exactly more likely to win it than Barcelona are and who cares about winning the French league.
They are different types of players and attackers but I would rather have Kane in my side if I had to choose one. One is a world class goal scorer the other a world class attacker and for me goals always comes out on top. Neymar may be the more beautiful player to watch, although again subjective because watching a world class goal scorer scorer a monstrous number of goals of all types like Kane scores is the best entertainment in football, but you can't really say Kane isn't in his league. Kane now is in that sphere regardless of trophies won so far.
Both are world class players. Kane is pumping out Messi like numbers in the most competitive league in the world. That gives Kane the edge.
Neymar is where he is based on the merit of being a key component in a NT that goes deep into international tournaments as well as for doing what he did when winning a CL at Barcelona. Nothing whatsoever can replace proof - a bottomline of a player who has gone all the way to the pinnacle of a competition, held his own and aided his team in winning the contest is how all greats are defined, or at the least placed in hierarchical order and it's precisely why many see a Maradona over a Messi until Messi at least proves he, too, can go all the way and win a World Cup like the aforementioned did.
Proven winners go for more than those who still have it to do. One of the reasons Ronaldo was worth what he was is that he'd shown what he was capable of when United won the CL - at that point, you're getting a tried and tested winner. It always makes a difference, and so it should.
Kane had the most goals in a calendar year for Europe, which is incredible, and not something that can be taken away from him, but the goals of Ronaldo won a CL and La Liga, the goals of Messi generally win trophies. Are all goals measured equally? Not really - they never have been, so Kane still has more to do even if he's in the ascension to that class people reel off as the elite without a pause for thought.
Anyway, you can't just nix Neymar's trophies because Kane doesn't have any - Neymar is meeting the bar that is demanded of that level and Kane has to do the same thing to become part of that level. As noble as it might be to stay at Spurs, if they're not a trophy-chasing team, Kane can never prove himself at the levels required to lay claim over those that do season in and season out. Neymar's record deep in competitions can be used for or against him; Kane barely has a profile on that level, so obviously it has to work against him until he does as that's when the playing field evens out and he can be scrutinised with the same fine-toothed comb the elite are every season that they play.
This is not singling Kane out, either, as I mentioned how Messi (and everyone else) gets it, despite being the best player of his generation when he's put up to scrutiny in the bracket of player he belongs to.
