Well no but when things have evidently been poor all first half that to me suggests a change is needed at half time.
Reading and watching ssn, out worked is the verdict so far, so like i said , that suggests a change is needed.
I am somewhere between the two. He has not had his best game and we are playing him further forward than he is suited for. However he is our playmaker and he makes more forward passess than most of our midfield.
