The manager has gone - Long live the manager
I understand your pain, but in time it will pass. He has been given possibly the best job in football, and I'm delighted for the guy. Had he gone to Sunderland, I would have been 'sad', but for me, it's like seeing somebody you care about go on to great things, so all the best to him, and I'm a little proud that it was 'our' manager that was considered the best by a club who could have hired God himself to manage them. I was initially disheartened, but now I'm coming to terms with it, and determined to embrace what ever happens with as much positivity as possible.
For once, all fans should get behind the club, wish Moyes well, and support the next manager with as much enthusiasm as we did Moyes.
