vaughan will leave unless he has had a dramatic change of heart. and it's not as if we need to spend all our budget on another centre forward! £5m would, i imagine, secure hooper this summer. if we are talking about a budget of somewhere around the £20m mark then we have £15m to spend on other areas. even this year we had four strikers and because the quality wasn't always there we had to persist with holt even when his form dipped. RvW is an accomplished player but he will also hit troughs and holt is not the same player he was and his future is not clear cut by any means although i'd prefer to keep him. if hughton can get another striker he will, no question about it. he tried to buy BOTH RvW and hooper in january remember!
I don't know why you're so certain Vaughan will leave. I've only heard rumours that he's not happy and I'm convinced that a word or two from the manager plus some proper first team game time and most players forget that they're homesick. If you know something more than that, fair enough

If Vaughan leaves (including on loan), then I agree that we'll definitely sign a striker. My post was based more on the idea that Hughton may look at Vaughan and think that if he wasn't already signed for us, his sort of return in the Championship would be exactly the sort of striker we would be looking at.
I disagree about Holt. With us playing more aggressively, with more support from the midfield, Holt scored three goals in three matches. I think he's no worse a player than he was last year. I think his future is pretty well assured (though I accept we might use him as a makeweight to sign another striker).
As for your calculations re. our budget - you are essentially saying we should spend 25% of it on a striker, when we have already signed two since January. How much more useful would that £5m be used on the midfield? I'd say it would be much more worthwhile than signing yet another striker. On which note, yes, Hughton did try to sign two strikers in January and, indeed, he has signed two since - Becchio and RvW.
I really don't want people to get their hopes up here. I really feel that the only way we will be signing another striker is if Holt, Vaughan or even Becchio leaves.
you've got me there rob! maybe i should change it to 90% sure. got a bit carried away with the old 9's
