Its more the process mate, it leads to instability and a lack of consistenct with no coherent phsipopehey. Im sure there are players in that dressing room who have been through what 8-10 managers, who must say to themselves when a new one comes in "oh right - you wont be here in 6 months" and wont be motivated no matter who it is.
The other thing is the use of resources, we are brining in lads right now with Dyche approach in mind, we brought players in under Lampard for how he wanted to play and same with Benitiez, carlo before - its just a waste and a mismash or resources. Its ridiculous.
We need to stop it - when we started sacking managers we were competitive for Europe, these days wed bight your hand off for 17th.
