Your presuming the philosophy works from day one and continues to work. And it also depends who the player is. Would you be happy, for instance, if we got a £2 million loan fee from West Ham for Andy and signed Danny Graham?
you have to believe your philosophy works, otherwise it's not really a philosophy, it's just a hunch.
Rodgers believes this philosophy works.
maybe it will, maybe it won't, but the point is, if you believe in it, then you've got to use every available resource in giving that philosophy every chance to succeed.
if people are saying that all Carroll offers us is a big fella we can use to ruffle defenders when things aren't going our way, then that's a pretty expensive option to just have sitting on the bench for most of the season.
we could easily spend 4 or 5mil on a player that could give us that option, it doesn't take 15m worth.
as for the west ham loan thing, that would depend on how much we ultimately got for him and what we spent it on.
