Couple of interesting links:
Right Result goes through each Premiership match and gives the "right" result, based on incorrect refereeing (i.e. taking off goals that were offside or scored from penalties or freekicks that shouldn't have been giving, and adding goals on for penalties that weren't given or goals that were unfairly ruled offside). You can see how the Premiership table would look if the referees got all the major decisions right. For all Arsenal's whining and complaining, they'd still be second.
BBC's Predictor let's you predict the results from now until the end of the season, and tells you how the table would look come May. I had United top, Chelsea second, Arsenal third and Liverpool fourth. Bolton and Fulham finished in the dropzone with Derby.
