1. Not 'facts' at all, but suppositions. Unless you have access to the boardroom and their Powerpoint slides.
2. The budget is likely determined by player sales, eg if Thorn can sell a player then he gets X% back to spend. That would be keeping the consistency of the transfer budget, and also reflects the actions of the past two years.
So you're complaining about AT not having the same wages to play with, yet then readily admit that he was given the wages to offer big contracts to Marlon King, Aron Gunnarsson, and Kieren Westwood. Don't you think that's a contradiction?
You're just creating a story instead of looking at the 'facts'. If, say, Thorn was told that transfer funds were dependent on player sales, then he would have known exactly what he was working with. I don't understand why you'd think SISU would have to lie about the available funds to a cheap, rookie manager who must be eager for his first job. It's not like they were trying to tempt Fergie away from Utd.
Not a fact.
That's just it - I don't know. Nor do you. Maybe, just maybe, he was promised more money to spend than he was given. But all things considered, I'd be very surprised if a) Thorn was promised any money without player sales first, and b) as somebody who scouted for the club and saw what the SISU transfer policy was like, Thorn expected anything more.
