Allardyce and his rather large mouth

Why does this guy always want a say in just about everything?

I was reading the Sunday papers and I think he was in every one of them running his mouth on how things should be done differently, what other managers have got wrong and how football ought to be played.

He even give his verdict on how to beat Barcelona claiming 'there are two ways to beat them'

Honestly, the man baffles me. If there was an article regarding the colour of Rick Parry's next tie then i'm sure he'd be the author.
