Owen is baffled by some former teammates who say Carrick should be cut loose at the end of the season.
He told casino.org: “Imagine if you got rid of Michael Carrick, just imagine it, and you brought in whoever – I don’t care who it is, even a born winner, somebody they’ve already had, that type of manager.
“Imagine if things started spiralling, started going poorly again; the ownership would get absolutely lynched.
“I’m astounded by certain people saying no, they shouldn’t appoint him. Astounded. Why on earth is this even a question? I don’t get it.”
He added: “I’m not saying go and give him a 10-year contract, everything’s perfect. But bloody hell, what more can he do? You’ve just got to let this roll.
“This Manchester United team look like they’re on the way back at this stage. Why would you interfere with anything?"
