Controversial but not simply for the sake of it, unlike most of the press these days. Mainly because he, and please forgive the cliche, calls it as he sees it.
The Djemba Djemba incident was crudely put but folks calling him racist based on if they already disliked him was idiotic.
Odd that managers are lauded for winding up animosity (slur, maureen) , or it's completely ignored (moyes - the peoples club) whereas someone who upsets folk because he says there team isn't very good to watch or that a manager is a bit of a bully is seen as controvesial.
Good luck to him, 5 live will be less interesting.
