My concern with someone like Dyche isn't so much that he's an unfashionable appointment but that his skillset has been very specifically developed and wouldn't really suit our needs.
All credit to him at Burnley - he took them up in his first season (I think?) and then, after an inevitable relegation, he went on to immediately win the Championship, which is a difficult thing to do when you consider the level of motivation he'd have to instil in a squad that had just faced a brutal reality of not being good enough for the PL.
Last season and the start of this he's done well to pull them away from the relegation places. And when he brought Burnley to Goodison a few weeks ago you could see how he's done that: set up your team to neutralise the opposition and hit them on the break. He's shown himself to be good at developing a system that works given the limitations of his squad.
The thing is, this only really needs to work 10-15 times in a season for Burnley because, with the greatest respect, anything above the bottom three is satisfactory for them at the moment.
This shouldn't be what we're looking for in a manager, for many reasons: our squad, uneven as it is, still has too much quality to deploy those sort of tactics; we supposedly have the resources to attract good players; and the stated ambition of the board is to play in the Champion's League. And, more than any of that, we as fans should at least be able to look forward to seeing expansive and exciting football rather than the reactive sort of a side that is primarily looking to avoid defeat. We had that for a large portion of Moyes's tenure and I don't think we need to see it again.
I get the appeal of a 'steady the ship' sort of coach but I don't think it's necessary for us, despite the fact we're in the bottom three. Koeman had a good squad at his disposal but couldn't figure out how to make it work. A talented and ambitious coach, even with the absence of a top striker, should be able to get a winning system in place. Dyche just feels like an unambitious compromise - which is exactly what Koeman felt like 16 months ago.
