Bit of an odd thing to say. Trendy Levy-Bashing as per norm.
Roberto Martinez's longest job is 4 years - of which he had 176 games and won a whopping 51.. (29% win rate). AVB won just 7 less games in 96 less matches and yet the majority call him a flop.
Redknapp would have had the exact same job length or longer (he was about 4 months short of 4 years) if he'd known a little more about loyalty.
I'd wait for the 2nd season before I judged Martinez, personally.
He's inherited a defensively minded team and built on that with his own attack minded approach.
When the Moyes legacy of that team fades it will be interesting to see if that part of their game suffers. Wigan had some truly awful losses, almost to the point of being defensively naive
