I don't recall the last time an Everton manager betrayed us, most of the time they were relieved/sacked... the pragmatic view obviously because these managers can't get another similar job easily and they want their compensation for being sacked.
Some people might say Moyes betrayed us - but he gave it a good go (10 years? 12?) and he was out of contract at the end of it.
The perception is that Carlo ran from the job. There was a recent poll on this forum that said 85% wanted Carlo to stay on next season. We were all supporting Carlo despite the turgid football. He abandoned everyone. I think he went early, if he gave it 2-4 years and didn't get anywhere, I don't think people would mind so much. And look what he did to James and Allan, players he brought in and then left them after one season. Allan moved over with his family I believe. He already had 8 years in Italy. James obviously wouldn't be here if he knew it was just one year.
And sure i get the shouts that its Real Madrid and you can't reject them but i for one hate the perpetuating cycle of classism, if we all just continue to help Real Madrid by selling them players and managers then we can never overcome them. And it would have been nice for Carlo to reject them, but that's obviously not realistic.
