I've read one by him, and one by a journalist who covered United every day for a couple of years. Both excellent. I'm guessing you have too? It makes you realise there's a hell of a lot more to him, a lot of it good, which makes the "he's a cheating, moaning bastard" comments all the more ridiculous.
Indeed.
He did a couple of season diaries in the 1990's, one including the Cantona 'incident'. They are both really good reads.
You can borrow them if you want - let me know.
