It'll be someone who wins the World Cup though, so that probably rules Kane out. For me I think the best players in the world this season have probably been Bayern's front 3, PSG's front 3, Vitinha, Rice, and Yamal. Given that PSG are likely to win the Champions League, their domestic league, and France are likely to win the World Cup, that probably means that either Doue or Dembele will win it. There's a nightmare scenario where Declan Rice wins it though.
