You’re missing the point.
The debate is, Monk is doing a better job than Smith. Smith has had, what 15 games, and joined part way through a season, Monk has had 43, including a full summer window.
But anyway, yes we have spent a lot under the previous managers, have all of those purchases worked out for us? No...it doesn’t matter how much we spend if the style of play/tactics/morale etc is all wrong. This is what Smith is having to change - notice how barely anything was spent in the last window (his first window with us). And just because Birmingham haven’t spent anything doesn’t mean they don’t know how to play as a team with some decent players...
it really is a stupid comparison, and to say that Smith isn’t doing as well as Monk is just rediculous.
