I find it impossible to refer to Peter Beardsley in negative terms. He has been an outstanding player for club(s) and country. Watching him at his peak for us in the Nineties must be some of the best football any of us has ever seen.
However, I think his football was instinctive. A gifted player with pace and control. As a communicator, he struggles. I think that probably means he'll never be much of a coach.
For us, he needs to be a Bobby Charlton figure, accepted for his footballing genius past but meeting and greeting, shaking hands. Being an icon. He has proved beyond any doubt that he was a great footballer. He and we should leave it at that.
If anything its harming his reputation him being such a shite coach. He should have done as you said Harry and been a NUFC ambassador, because as long as he has a hole in his arse he will never make it as a coach.
