I don't doubt for a minute that he works his arse off, cares deeply for the club, desperately wants to succeed and try to analyse things when they go wrong.
But it's clear that he cannot analyse himself so well anymore and his best isn't good enough to do anything other than maintain the status quo. That is key part of any self-analysis he cannot face up to.
Funny that in 25 years Fergie never faced the same questions....Why because he was his own harshest critic, always striving to beat the rest, to change, to adopt new ideas. Not Le Prof....he knows everything apparently.
