Manchester City are three points behind Sir Alex Ferguson’s side but the Eastlands outfit can move to the top of table on goal difference with victory at Eastlands.
But the Red Devils midfielder does not believe the clash will decide who will win this season’s crown with two games still to play after Monday’s clash.
“Whatever happens, the title race won’t be over at the final whistle,” Carrick told United’s website.
“Obviously we’re the two main contenders and this is going to be a big three points, but there will still be two games left to play.
“And the way the last couple of weeks have gone, I don’t think you can look at the derby as a decider.
“Who knows what might still happen? We can only look at this game as an opportunity to win three points.
“Don’t get me wrong: it would be a massive step towards the title if we win, but it won’t hand us the trophy.”
Carrick has already won four league titles since joining United from Tottenham Hotspur in 2006, and the 30-year-old admitted he has grown accustomed to dramatic title races.
“Every time we’ve won the league since I’ve been here it’s gone right down to the last couple of games,” he added.
“We’ve never won it with loads of games to spare. It just doesn’t happen.
“Throughout the season you drop points and you can drop points at any time.
“We went on an incredible run after Christmas and put ourselves into a good position.
“And we’re still in a good position. We’re three points in front with three games to go. I think some people have forgotten that!”
