"Duncan and I fell out at the end. He chose not to shake my hand when he left," new Manchester United boss Moyes said of the now-Toffees coach.
"Duncan went into exile. We'd see each other the odd time, but there were no pleasantries.
"Then I got a call from him and he asked to see me. He said he regretted every day for five years that he didn't shake my hand, so we made up.
"He is a changed man and he works at Everton day and night."
