Herd, I don't think anybody has "fallen at the feet..." of Pat, but he has served the club well for a very long time and deserves some credit.
Many of us will have wished that Pat would be able to influence AW to make changes but we can't be sure that he hasn't tried.
We don't know what his job description is, what role he does or doesn't play etc and AW will always make his own mind up, so it will be very difficult to know what effect Pat has had.
Also, I'm not aware of many Assistants getting their bosses to change their ways.
The influence that the Arsenal No.2 has may become evident when the new man takes up his role, but I doubt we'll see much change.
