I could see Eddie Howe being of interest for the board. I think that they could see him as a project manager.I think we can all accept defensive/counter attack football with results but it's being able to sustain it every week... and it's something we can't.
I would say Ten Haag would be my choice. Think we would have a better chance of getting him from Ajax than we would say Nagelsmann from Leipzig who is more than likely eventually destined for Bayern/Dortmund/Madrid in the future.
Another shout when it comes to an attacking manager is Bosz at Leverkusen.
