Manchester United manager Alex Ferguson has said that this month's derby clash against Manchester City could decide the Premier League title.

The Red Devils moved five points clear of their bitter rivals with Monday's 2-0 win over Blackburn, but Ferguson still believes the derby could be a key game.

He told radio station U105.8fm: "Derby games are always important, and it could be even more important this year.

"It's bound to have an impact on the eventual winner, albeit that we're going into it with a nice, healthy lead."

United and City will go head-to-head on April 30 at the Etihad Stadium.
