Last season Martinez inherited a solid defence from Moyes, this year age has caught up with Jagielka and Distin and they have deteriorated massively and he hasn't got a clue of how to change it.
Nah, too simplistic. Martinez inherited them, yes, but they played an entirely different way - the solidarity last year had little to do with
Moyes, it was more to do with talented players blossoming in a setup that allowed them freedom to play and display their talent.
Problem this year is a ludicrous pre-season combined with baffling tactical decisions that remind everyone strongly of why Martinez at Wigan was ridiculed for his defensive setup. Now all momentum has been lost - and to be honest late last year there were signs of the decline.
Martinez deserves every ounce of criticism he gets for this - the test of him as a manager is how he bounces back from it. That side should never have been selected tonight because in terms of momentum for an important run of league games there was too much to lose by risking a thrashing like this.
