Wolves manager McCarthy has stressed all along that he wants to keep club record signing Doyle who moved from Reading for £6.5million 12 months ago.
And McCarthy is adamant that it will take an outrageous type of bid for him to offload Doyle.
McCarthy said: "When Kevin said recently that he was pledging his future to Wolves it suddenly caused a stir.
"The reality is that he was saying it to get everybody off his back.
"Leave him alone and let him play his football.
"Look, if Manchester United come in and offer the club £50million and give him 200 grand a week, I can't keep him.
"Then I'll have to say 'thanks, Kevin, all the best, see you'.
"But no, there's not been any approach from Arsenal - I can't be any straighter.
"Doyle will be a player for us unless someone comes in offering the earth, moon and stars for him."
