See, im not sure i agree with that. McGhee finally found a team and a system, might as well keep them on the park as long as possible, build the confidence and let them play. What if he brings on a couple of ringers, it messes the system, we let in a couple and the confidence takes a big dent.
I think on this occassion he did the right thing. Once we have put a few wins together and the team are going well, then yes, bring the boys in at the appropriate times. Today, keep them on the field and build that confidence and understanding.
