I'm sorry but unless Col is absolutely knackered me personal view is he has to stay on.
People were saying on sat "Why is Senior coming off? Cols not done much for last 10 mins" When moments earlier he threaded one of the best through balls i've seen in ages through to Senior, where the keeper just beat Chris to it.
Col often comes towards our midfleild to the pick the ball up and has the class to often switch the ball to the wing.
Basically what i'm trying to say he is a really intelligent footballer who is our inspiration when attacking. Without him like against Luton we are one dimensional.
I say Col has to play full 90 if fit.
However, I'm happy as long as any THREE of Senior, Little, Johnson or Elam or on the pitch at anyone time. Beats previous seasons of often having one attacking player on the pitch.
