The 31-year old midfielder has produced arguably his best season for the Red Devils in 2012/13, gaining selection to the PFA Team of the Year, and helping the famous club win their 20th league title.
Carrick has often been criticised my certain sections of the media but he feels perhaps his improvement in recent times may get them off his back.
"Yeah, I feel like I've improved all the time I've been at United," Carrick told the club's official website.
"You're always going to have better spells than others. That's natural and you can't be on an upward curve all the time or play at your best all the time.
"But as time has gone on I have improved as a player and I'm still looking to improve even now. You have to here."
He added, in regard to the media scrutiny: "It makes me laugh sometimes with the things I read and comments I hear.
"Perhaps a few more figures in football have said nice things about my game and then people jump on that. But I've been happy with my form for a while now."
