He should be performing far better with the personnel he has, even discounting the results we need to see the team actually playing together as a unit which is possible regardless of the formation and selection, but seems to evade us almost every week.
I remember watching the Fulham (I think) and Swansea matches last season and actually thinking that he'd got us playing well as a unit, despite the results, and was happy with the games. The vast majority though - even in our 5th place season - we've looked flat as a fart win, lose, or draw, and it's everything to do with the management. Whether that be Pardew, the coaching staff, or both.
