Time is changing. A year is a long time in football these days. During this time one should see progression. Continuity is only good if it provides progression. I think a reasonable expectation is 60 points, and that we see a clear direction in our game pattern.
What is worrying is that the curve has started to go down, and there is a negative correlation between results (and performance) and how many games Ancelotti has been manager. He is dependent on getting positive results again pretty quickly.
A point average of 1.58 is to be expected, which gives 60 points. This season the average is 1.55, and we are not far away. But as mentioned, he should start winning games again, and the next 6-7 games are tough.
Ironically, we meet Arsenal in 3 games, and if the results of both Everton and Arsenal have not improved, this match could be crucial for one of the managers (especially Arteta).
