"He is doing a very good job," said Moyes. "He has very good players there. I always told them they could play without a manager because they are very well organised.
"But Roberto is doing a really good job keeping it going.
"I had a great time at Everton, it was a great club for me at the time in my career when I left Preston North End. They were fabulous to me - they gave me a chance to succeed the best I could at the club. We had one or two early years at the start when it was a bit up and down but overall we had a pretty good level of consistency after that and tended to finish pretty well in the division.
"I don't think it's any advantage there's a new manager there and he's got his own players in as well. I do know a lot of them, I probably brought most of them to Goodison, if not them all, except for the recent ones. They're all really good players and I've got a lot to thank them for because they helped me to win games."
