If there is an exodus, Barton is leading it.
Why mention Jonas in his tweet?
I don't buy for a second Nolan will be gutted to leave, I reckon he was sounded out that West Ham were offering him a 5 year deal and with the advantage of knowing how low the current board's stock is with the fanbase he was in a no-lose situation.
Him and Barton are playing the martyr card superbly.
