Mirth haven't you heard, that's the recipe for how we could never have signed any player we didn't sign.
If they moved to another club: we couldn't have signed him because he moved there.
If they didn't move to another club: He didn't move anywhere else either, so we couldn't have signed him OR he didn't move anywhere else either, so he clearly wasn't a good player yet. Nobody could've foreseen that he would become good enough.
