They're never going to please all the fans. The new owners shouldn't be trying to. They should be picking people who they think fits their strategy for the club.
They've got a manager who has lots of PL experience, who has taken on struggling clubs before and got a tune out of them, who can work with limited resources but who has a very extensive knowledge of players (given they don't seem to put much faith in Thelwell). Additionally the two interim managers were players he has a long relationship with. He knows the ground, the training ground.
It's the safest possible appointment and one that they've made very quickly.
