Good chance that it tell a bigger part of the story than the opinion of completely uneducated fans.
It's not whoscored which is limited, it's a company that is a leader in the football data analysis field. As far as I'm aware they use numerous metrics that assess a lot of the things that fans don't pick up on.
Personally I'm not a massive fan of Mount because I like end product, like most fans. It would go some way to explaining why Lampard keeps playing him and why England like him so much, having him ahead of guys like Maddison and Grealish.
