Carrick was Middlesbrough manager when Rogers was sold to Villa.
Ahead of Sunday's clash with Villa, Carrick admitted: "First of all, it is fantastic for him to see Morgan going on to do so well and for a good period of time.
"He had the initial signing in the January, and I wasn’t really sure how it was going to go, it was a big step for him, he hadn’t played for an awful long time at Middlesbrough so I felt he could have done with a little bit more.
"But as soon as he has gone to Aston Villa, he took huge steps and became a major, major part of their team and part of the England team so that is how well he has done.
"You could always see what he was possibly going to be capable of and the potential in terms of his attributes, the way he carries the ball, he can play off his left foot, play off his right foot, create and score goals and really good athletically.
“So there were a lot of things there when we took him to start with but to see him go on and have such an impact would be probably more than I would have expected or probably more than Morgan himself would have expected.
"It is great to see though. I enjoy seeing him do so well. To come up against him is a different story. Nevertheless, he is a good person, great to work with so I am delighted he has done so well."
