Poll of the day: Who will win the Manchester derby?

If Sir Alex Ferguson's side take all three points they can all-but guarantee a record 20th league title, whereas a win for Roberto Mancini's side will take them top as they bid for their first top-flight title since 1968.

City seemed to be running away with the league earlier this season, and at one stage held an eight-point gap over United.

That lead was eroded as Sir Alex's side went on a run of 12 games unbeaten, and eventually took a five point gap of their own. That lead is now down to three points, with a resurgent City side (led by former United player Carlos Tevez) putting down a marker with a 6-1 win against Norwich two weeks ago.

With form supposedly 'going out the window' in games such as these, it is a tight one to call, so who do you think will win?
