It's another vote for Vinnie Jones for me. I remember when he made his debut, he was going round the pitch doing his he-man thing to the crowd before kick-off, and my mate said 'All we need now is Kent Walton on commentary'. There was just something ineffably cockney twattish about him, even if he is in fact from Watford. Whilst I get the argument that we needed a midfield 'enforcer', I'd also say he cost us points because refs took one look at him, decided we were a team of cheating thugs, and ruled all the 50/50s accordingly.
(For younger posters, Kent Walton used to do the commentary on Saturday afternoon wrestling, which in those days consisted of gay bricklayers in spandex leotards bouncing off the abdomen of a morbidly obese gentleman from Bradford.)
