The veteran has been rewarded for yet another superb campaign with an extra year's contract with the club until June 2014 which will see him complete his 23rd full season as a first-team player. And Carrick says the 39-year-old thoroughly deserves it.
"He sets an example - and has done for a number of years. He is Mr Manchester United," Carrick told us.
"He sets the tone around the dressing room. He doesn't say an awful lot but when he does speak, everyone listens and everyone respects him. It leads onto the pitch.
"Not many people have lasted as long as Ryan. You have to take it year by year and see how your legs hold up. He is a one-off.
"It is not just that he is still playing, it is the way he has adapted his game. In his younger years he had a totally different way of playing than he has now. To be able to do that can't be easy. It shows the qualities that he has."
Michael was speaking to ManUtd.com, PA Sport and BBC Radio.
