Disagree. Kaz is great in a free role and when you have 3 central mids you should be able to cover for him at any given opportunity. Kaz cutting in must scare a lot of defences, down the wing continuously is too 1 dimensional.
Then we beg to differ, a true 'free' role would indicate Kaz also looking for space on the right, which I rarely recall him doing. Tactical nous, for me, is his weakest attribute and twice we were exposed when he wandered to the middle. Bridcutt and Ince to a lesser extent are holding midfield players, so any time they leave that area of the pitch we are considerably weakened, as was the case when he lost the ball in midfield.
I like Kaz going down the line or cutting inside on to his right foot. On his day he is devastating.
