I wouldn't mind Martinez tbh!
Even though Wigan have been down the bottom of the league A LOT. He occasionally plays nice football and has signed a few decent players while at Wigan.
With a decent defensive coach, or better defenders at his disposal, he could do a job here.
But I do think he loves Wigan because of his history with them. However, if he was to come here, I reckon he'd be a pretty loyal manager, sticking with us, much like Moyes has with Everton.
