Your guy will run out of money and interest quicker than Randy Lerner.
If Koeman is taking a step up and Everton are aiming higher than we are, that's top 4 then.
You won't do it. At best Top six a couple of times then your sugar daddy realises he's having to pump in £100m every frigging year and the fanbase start grizzling when you don't and then it all goes to sh it.
Hopefully you will concentrate on getting the stadium built because your current toilet needs some work and that's what will really set you up, not ludicrously overpaying for a manager who is perfectly fine but not worth nigh-on Mourinho money.
Good luck.
