The simple fact is the guy does not have a clue what hes doing.
We have played Arsenal several times now and Wenger is tactically too much for him every time and bob has absolutely no idea what to do when things don't go to plan A.
The fact today he brought on Stones for Besic sums it up, we're losing 2-0 the last thing you do is bring another defender on and go 5 at the back, how is that going to help us create chances, we then left Cleverley and McCarthy as a lone 2 with Barkley being Arsenals 12th man today, Lukaku isolated and frustrated at the rest of the team and Lennon non existent for large parts of the game.
His game management is arguably the worst ive seen of any manager, 2-0 up winning comfortably has happened a fair few times this season and every time a change has been made which has killed the game and not in a good way, he throws it away by continually attacking and then today at 2-0 down he brings on a defender .... What is going through his head to think winning comfortably = more attackers and losing without any attacking threat = more defenders.
Hes the modern day footballing equivalent of Houdini, every time he looks dead in the water he gasps for air right at the end with a victory or a cup run to give hope when the honest truth is, we have no hope of going anywhere, we are about to lose a few big names this summer cos who would want to stay playing for this trash and the only way is down as long as he is in charge of us. He's a cup manager and thats it, brings nothing else to the table anymore except for some good ideas involving training upgrades and a friendly family personality in the public eye, everything else he is below par as a manager and would be lucky to get another job like the one he had at wigan.
