All this talk of whether 'he got the club' or he understood us is interesting - I used to wonder whether it really matters that much, but the main point is that the manager has to inspire confidence. We are all like minor shareholders, who put in loads of money, and just need some hope and excitement in return. In a way we are getting nothing but hope and emotions for our investments, but we want at the very least someone who looks like they want to be here and want the best for us. That's why I always liked Martinez, and I'm sure he was really depressed by the way things worked out we were too. Not only does the manager have to get us, but we have to get the manager too...
Moyes understood but was limited by his own tactics and no investment, and we kind of sympathised because we knew he did his best, mostly, and he made some great signings.
Martinez definitely understood, but didn't have the coaching staff and tactics to be physical and solid when it mattered (but his 3 years was better than how he is remembered) We got his idea, but thought he was naive, and we want fighters as well as stylish players
Koeman - I think we have to let him off the red christmas tree, but he never talked a good game, or good tactics. We also never could see what he was trying to do, and ultimately never saw any example of what 'Koeman style' football was. He looked like he was a consultant
Allardyce - behaved like he was too good for us, and still is spinning a story about it on every interview he gets, to try and secure his next job. Super annoying.
