Well, as you will see below, we are currently 5 points better off than we were last season (the third season in a row we have shown an increase). Note though that, of the 3 games left, we only got 3 points out of 9 from the respective games last season (we beat Coventry, replaced by Blackburn, and lost to Spurs & Ipswich)
For the record,
Arsenal are currently 8 points better off than last season with a tally of 4 further points from the respective games last season
The Mancs are currently 4 points worse off than last season but with 7 points further gained from last season's respective scores.
Newcastle are 4 points better off than last season with 3 further points projected.
So in summary all the top 4 sides are on course to beat last season's tallies but it's Arsenal who have improved the most which probably explains the likelihood of they becoming Champions.
