Earlier this week, Rooney admitted he would love to be part of Carrick's coaching staff at United if asked.
"Of course I would. It's a no-brainer," he said. "I'm not begging a job here by the way. Just so everyone knows, if I was asked to go in of course I would. Appointing the manager is the most important thing."
Now, the ex-Everton man has revealed he would only return to management if United or the Toffees came calling. He also revealed a little titbit about Carrick, too.
He said on Football Focus on Saturday: "I said last week, if Manchester United called me to go in in any capacity, I would gladly do that. I love the football club and I was there for 13 years and it's probably one of the only two clubs I would go back into coaching for in Manchester United and Everton. I know that's with Michael [Carrick] as well. Michael had offers from other clubs and I know 100 per cent there's no way he'd go into any other football club as an interim manager or head coach other than Manchester United. So that's what the club means to him."
