He and Martinez started the rot imo, although at least Martinez tried to aim for the top.Mainly because Koeman absolutely destroyed this club.
Silva was the right man at the wrong time, Lampard was pleasant but useless, Benitez was a proven winner but wrong on so many levels however kudos to both us and him for at least giving it a try, took balls on both ours and his parts, Allardyce did what was asked of him entirely unspectacularly and Ancelotti, while great at one point, totally left us in the lurch at the first chance he got.
Dyche for me did better than expected, kept us up in six months, then had to do the same with two points deductions given for reasons he had no hand in creating, all while with no money to spend and an absent board.
Then my hero and saviour, David Moyes MBE. Tremendous guy, love him. Whatta man. Whatta mighty good man.
