Asked on Friday if he had sympathy for Martinez, Moyes said: "I definitely do. But I also know that if I was the Everton manager and Sir Alex had come asking for Baines and Fellaini, I would have found it very difficult to keep them.
"I always felt the right thing to do was what was right for the players.
"I respect Everton greatly and I don’t want to do anything that would in turn affect them.
"Of course, taking their players would affect them but I am certainly only doing what I have to do in my job."
