Manchester United midfielder Michael Carrick doesn't believe tonight's derby at Manchester City is a title decider!

Sir Alex Ferguson has labelled the encounter between City and United at the Etihad Stadium as such, claiming it is the most important derby he has been involved in during his 26 years at Old Trafford.

"Whatever happens, the title race won't be over at the final whistle," Carrick said.

"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."
