I just don't see how its somehow 'Ashleys fault', or 'Ashley will benefit for his Xmas drinks' from this.
It's not rocket science that we have (or had) too many goalkeepers on our books at the moment; Elliot, Rafa's choice at the moment; Darlow, seemingly his 2nd choice senior player; Krul, not wanted, possibly due to him having recently recovered from a long term injury and not considered good enough right now; Selz, a Rafa buy who has not (at least yet) met expectations (and may never (though De Gea also fell well below par initially)); and a promising youngster.
Rafa can only have 25 senior players in the squad, and four goalkeepers is at least one too many; two too many if he is considering giving the youngster his next step-up, as I suspect with him being on the bench for games recently.
This is a logical decision by Rafa, the Club as a whole, and not relevant in any way, to Ashley.
Ashley (rightly) gets blamed for things which he deserves; why have a pop at him for something other? This is where he gets some of his strength from.
