Everton will take on United away from home at Old Trafford in the Premier League in a few hours’ time.
The former England international forward was hugely successful during his time at Old Trafford and is a United legend.
Former Everton and United manager Moyes has suggested that he would not be surprised if the 31-year-old, who can also operate as a midfielder, scores against the Red Devils.
“I think Wayne will be far too respectful of United to celebrate on Sunday if he scores,” Moyes told The Mirror. “He knows all eyes will be on him.
“But he will be aware of the importance of the game for Everton. He’ll be up for it and I don’t think anyone would be too surprised to see him score at Old Trafford.”
Former Liverpool and United striker Michael Owen has backed Jose Mourinho's side to pick up all three points from the encounter.
“The game also sees in-form Romelu Lukaku face his old club for the first time and I can’t see past a comfortable home win despite the absence of the influential Paul Pogba from the United midfield.”
A footnote added: “Michael’s recommendation: United to lead at halftime/fulltime at 21/20.”
Meanwhile, Everton manager Ronald Koeman has suggested that defender Michael Keane is having doubts about his game.
Former United defender Keane joined the Blues from Premier League rivals Burnley in the summer transfer window.
"Michael Keane is maybe, on the ball, normally our best centre-back in our ball possession,” Koeman told The Liverpool Echo. “Maybe now he has doubts in his football. If you have doubts instead of going front in defending you make a step back.”
