Couldn't be arsed, i imagine the club already promise him back then so he can have place in first team slowly ala Foden.
But he doesn't want to wait and wanting first team regular football immediately so our club with no choice is selling him.
Lavia have no attachment for our club unlike Foden, Palmer, Lewis, McAtee etc, they are trained for our club since very young while Lavia is bought academy player from Anderlecht. Lavia only saw our club as stepping stone to further his career as football and nothing more than that.
