Malky, welcome to the board.
If you've £7m in loose change then please go ahead. That would be hugely over the odds for Austin. Rhodes was and is a much more complete player.
As I said earlier, for Austin £2m up front with performance related extras which could take it up to £3/3.5m is realistic.
Thats the trouble with this window business. If you want a player whose club does not want him to go, then you pay over the odds. Alternatively you may get someone whose club wants to get rid of and you take a risk on how they will fit in with your club.
We've seen that to our cost in recent seasons and that is why Malky (our manager, not you, unless..........) doesn't rush into signings in January.
