You're right, I can't argue with that and the depressingly low goals return that those two systems produced. Hopefully we'll see a change in Philosophy and style from Mr Hughton as well as the change in playing staff.
Apart from when he says he plays 4-4-2 but is considering moving to 4-5-1 or 4-4-1-1
