I'm not remotely "in the know" but I don't think I've seen any of this on any of our forums. I can't really see Nugent being any sort of a trouble maker and, don't forget both Johnson and Ince were around during our all too brief winning streak when McClaren first arrived and lifted us from relegation threatened to top 6. I think our current plight can be put down to:
Overrated and over paid players
Massive slump in confidence
Trying to find the best formation
McClaren having to recover from the damage done by Pearson
The "second" honeymoon period is now over for McClaren and, whilst we're in relegation right now, we've settled into our true position - mid table.
