His entire family got an interesting story.
His parents are both British expats, who seem to have fully adapted to life in Belgium.
William Still also has two other brothers active in high-level football management.
Edward Still, his older brother, is currently head manager KAS Eupen in the Belgian first division, having managed Sporting Charleroi before.
Both William and Edward seem very fluent in English, French and Dutch. Which is surprising given they grew up in francophone Belgium, but then again, their English background might have helped to learn Dutch.
And it doesn't end there. There's a third brother (also a ginger, they're like the Weasleys these guys/s).
Nicolas Still, is assistant trainer to Edward at Eupen but has some individual experience working as video assistant to Club Brugge in the past.
I genuinely wouldn't be surprised to see them end up at a major Premier League club. They're dual-citizens anyway, and will fit right in.
