Troops man, you have got to relax, you're going to give yourself a heart attack at this rate.
There is no reason at all to think he doesn't want Rafa here because Rafa wouldn't be here if Ashley wanted rid, he doesn't back him because he doesn't back anyone usually, the last manager he backed wasted his money (cheers steve).
Rafa is a smart bloke who does his research and knew who he was signing up to work for, he puts it on in public to pressure for budget or players in because thats the way to do it.
You talk about the way Ashley treats Rafa like hes an abusive spouse.
The reality is, Rafa is a manager working on a limited budget for his department, this happens in workplaces the world over and hes doing a fine job. Ashley isn't going to invest because he doesn't see value in doing so and because if he is wanting to turn the club over to a new owner he wont see a major return on investment for any long term purchases, we're going to see some loans and maybe one permanent signing if a couple of players leave (mitro and colback particularly).
More to the point, whilst we are indeed on a discussion board, you're melting down about this on a daily basis but you can't actually affect any sort of change so just sit back a little and calm down, its only the 4th.
