Groves should go with Shane McGuigen. But, I think his stable might be too busy at the moment. McCracken is a great option though.
Rob is too busy training AJ to take on George at the minute. George seems like he has taken a couple of punches too many recently and needs a new trainer or unfortunately a neurologist.
George Groves was at his best when Adam Booth was training him. Shame they can't work out their differences.
