Moyes has never beaten Mourinho in nine attempts in his managerial career - eight of which came during his time at Everton.
He will try for the 10th time on Sunday when Manchester United head to Stamford Bridge in the Sky Live fixture and Moyes has nothing but respect for Jose Mourinho's successes across Europe over the past decade.
"I have no problems at all with Jose," said Moyes. "We were never going to sell Wayne (Rooney), so my relationship with him has been fine.
"He has done a brilliant job wherever he has been. He is someone who catches people's imagination.
"The manager I have taken over from, Sir Alex, is undoubtedly the best of his generation and longer. Jose could well go on to be the best of his generation because he has been so successful in a lot of the jobs he has been in.
"I have only got admiration for Jose, nothing else. But I am competing against him and I am going to try and beat him every time I play against him. That has not changed."

You're just highlighting how utterly inadequate you are David, why don't you come out and say the truth, you were given a job you had no right to, Mourinho is the man United should have picked.- solskjaer99
