What does that have anything to do with Son being world class or not?On the Balon dor thread you think the highest goal scorer should get the award, still waiting for your answer to my question there BTW.
But to address you question.... It's not just the fact that Lewa scored significantly more goals. It's the fact that he was +9 goals above his xG as well. He was scored the most goals plus scored goals that were of high quality/difficulty meaning he was adding significant incremental value to his team.
