Carrick has only made one appearance so far this season, starting the Community Shield win over Leicester, but he believes the stiff competition for places is part and parcel of playing for United.
Carrick told Manchester United's official website: “People said to me, 'Someone's coming in in your position, will you be worried about that?'
"For me that's never, ever something I've worried about. I think you've got to embrace it.
"As a player, you do what you can, you do what you're good at. From the minute I walked into United, I've never changed my take on things.
"I've never taken my foot off the gas when I'm playing every week, I've never worked extra hard to get back in the team when I'm not. I just do what works for me.
"I think football's dangerous these days because from week to week, people get so up and down about things.
"But it's about the end game, what you're trying to win, what you're trying to achieve. That's how I look at it. Whether you're playing every week or you're not playing every week, you're part of the squad and you've all got to pull together.
"You want to look across the changing room and see we've got the best striker in the world, the best centre-half in the world, the best midfielder in the world,"
