Blimey, this debate is still going around is it?
I take me opinion from the many managers (almost double figures!) who have worked with him in the past few years and have all singularly failed to sack him. So really, how bad can he be? If he was as terrible as some people make out, he'd have been given the boot years ago. Every other fecker down Filbo Way has.
That leads me to the conclusion that he's actually not a bad goalkeeping coach. He was not a bad keeper. And if we're blaming the poor quality of our keepers on him, then we should consider that maybe they'd have been even worse under someone else. A frightening prospect!
