Carrick has been impressed with head coach Roy Hodgson after the midfielder decided not to make himself available for Euro 2012.
He said: "I have really enjoyed it. I think the new manager has had a positive impact on the squad.
"We are playing some good football. Everyone is enjoying it and I think you can see that from the performances.
"The competition for places is nothing new. There has been competition all the time. When I play, I play and enjoy it and do my best and see what happens for the next game."
