The striker remains a target for Chelsea.
Schmeichel told talkSPORT: "Wayne Rooney is one of the best players in the world. Manchester United are one of the biggest clubs in the world. Why on earth would we sell one of the best players in the world?
"Winning the championship this year is probably the most important thing for a long time for Man United. There's no Alex Ferguson anymore so we have to prove we are still competitive and we can still win championships. Why would you sell your best player, or one of your best players?
"I don't know what needs to be done for David Moyes to kill the story. He has said it many times that no amount of money will make him sell Rooney. Hopefully, he will stand by those words because he is such a good player and he is so important to Man United."
