I personally believe it's the uselessness of the defenders in front of him not Cooper. You can bring in McCormick, but I dont believe he will do much better, because he still has those same defenders.
I personally don't rate Fornah, I'd sooner see McLeod back. I don't rate Noublè at all and would prefer a Hardie/Jephcott combination and for the life of me don't understand Lowes love affair with Connor Grant when you have Camara on the bench.
My preferred line up is
M Cooper
Aimson, Opoku/Canavan, Watts
Edwards, Camara, McLeod, Mayor, G Cooper
Hardie, Jephcott.
For me many of the rest shouldn't even get anywhere near the starting line up.
