The original idea of Neville/Carragher was good when it was a tactical thing on monday night football (from memory), neither had been that long out of the game and were much more clued up than their contemporaries at the time. That was 13 years ago!
The worst thing about Neville though is what you have said, he loves his own voice and to take on the title of being a voice for people i.e. the super league thing where he tried to makeout he was some champion of the people. There's only one destination for people with money and who like the sound of their own voice, he'll end up in politics without a question of a doubt.
