Everything interview I've read with Russell Martin suggests he just wants to play the way he likes – dominate possession, play out from the back, score beautiful team goals, plan b is do plan a better etc.
It's vanity driven, inflexible, and has been found out spectacularly following the step up a division.
I don't blame Rasmus for thinking Martin was the man to get them promoted – it worked – but it goes to show how important it is to choose a manager who can adapt in the second season. You'd think someone like Rasmus would know all about the sunken cost fallacy.
