Playing Devils Advocate here.
If and a big if this is all real and goes ahead and whatnot, reading up about this fella i can see the outcome being something like this.
Initially we are more succesful, sign some good players and progress, perhaps even 'god forbid' get into the top 4 and into the champions league. then the money will kind of dwindle like it is now and the lack of investment will come to light again, despite the club being in a much better position.
Meanwhile, off the pitch a new stadium is commissioned and over time it finally gets built. The lack of money on the pitch gets connected to the new stadium ala an Arsenal situation but we all go along with it because of the new stadium we are getting. It finally gets built and nothing changes in terms of money, and it becomes apparent the owners are pocketing the money for themselves the whole time, except the value of the club has gone over what the owners paid so the asking price is balked at by prospective buyers. This then puts us in a no win situation, better run but no success coming from it.
