A lot of people, on various forums, are linking RK's frustration to the board, not supporting him with funds etc, but Ron is quite a straight forward type of guy, who says what he thinks.
I honestly believe, if their was an issue with the board, he would just say so, and that's the way it should be. People that hint at things, not being quite right, are often trying to deflect criticism from themselves, and I don't think that is Ron's way of doing things.
I think (hope) his frustration stems from his players making so many schoolboy errors, all over the pitch, on such a regular basis.
Nearly every match we are conceding goals/chances as a result of our own errors, rather than as a result of being outplayed.
It's the same at the other end of the pitch. We carve out 1 or 2 sitters, and 2 or 3 half chances every game, yet our conversion rate is abysmal.
Even our half chance shots, from outside of the box, are poor. They are snatched at or scuffed and rarely on target (Martina v Arsenal the exception) which shows a lack of composure by all of them.
TBH, I don't know why we can play as we did against Arsenal, then put in lesser performances against "lesser" teams, and I dare say it puzzles Ron as well, but I have reached that stage where 40 points can't come soon enough.
