Palace impressed in the second half of the 2013-14 campaign and beat the Toffees 3-2 on Merseyside, and Martinez has urged his troops to remember that defeat before taking their London counterparts lightly.
"I don't think that it is a transition period," he told reporters. "Neil Warnock has got phenomenal experience in the game, he knows the club and the players inside out.
"As a group they are clear in what they do, I thought they were phenomenal in the second half of [last] season.
"I expect exactly the same [on Sunday], I think we will see a team who know exactly what they are doing, using the strengths of the group."
Sunday's clash is scheduled to kick off at 4pm.
