Imagine thinking Pogba is one of the greatest of all time
I don't personally believe that. But the rule is well established. Pele and Maradona have won a world cup and Messi and Ronaldo haven't that's why they can't be called the best ever.
Now Pogba is a world cup winner he must be automatically better than anybody who hasn't won it.
Can only judge a player on international performance once every four years, and only if they win it
