The 30-year-old has come in for his fair share of criticism this term following a series of below-par performances.
But Ince told Paddy Power: "No one has a divine right to play for Manchester United.
"I don't care who you are. If you're performing to the best of your ability and you make the team, then you play.
"But there are too many Manchester United players not playing at the top level this season.
"Anthony Martial was outstanding in parts last year, but this season he's not on the ball.
"It might be that they're failing to understand Jose Mourinho's ideas, or they're struggling to play the style he wants.
"Everyone can jump the gun and say 'drop Rooney' because he's a stand out high profile player who isn't performing, but if you drop him who do you play instead?"
