To me his signing made all the sense in the world, when the club backed it up with THE striker.
When that signing failed to materialize, spending all that money on SD began to not make sense.
That wasn't help by being bombarded by the default setting of some posters replying:-
'well we need to replace Greer'.
Which is all well and good, only Greer didn't leave the Albion as a £4m rated defender.
While the club is saying it can't make the money work for a striker.
So far everything has worked out considerably better than I (and I'm sure many others) expected, so fingers crossed the team gets through the next half a dozen games, ready to gear ourselves up for January.
Football finance is a funny thing that I, and I suspect you, don't fully understand. We did need to replace Greer and so the money spent doing that is irrelevant (if a bit of a surprise). The need for this is separate to the striker need and I don't understand the link.
