Mackie is pushing for a recall after coming off the bench to score the winner in Wednesday's 3-2 home win over Liverpool.
He said: "When you're a pro and you work hard, you're very disappointed to be on the bench.
"I feel my performances have been good enough to play in the side.
"I've never been one to sulk and want to prove that I belong at this level.
"If you're coming off the bench you've got an opportunity. But like I say, I think I deserve to play.
"If I was the manager I would pick me."
