Of course Foden is better than Greizmann now. But peak Griezmann was elite, top tier stuff, the best French attacking midfielder since Zidane.
As for Stones v Varane. Your right, Stones is miles ahead at present. But when France won the World Cup, Varane was at this apex at Real Madrid.
Until our lads can actually do it. We have no business assuming we are better than France. We also dont have a player like Mbappe. Infact we have never had a Messi, Ronaldo, Zidane, Ronaldinho type player. A player who could generally lay claim to be the worlds best.
