Current form looks like this:
Us: PPG 2.58 which is good enough for a 98 point season.
City: PPG 1.92 - 73 point season.
A***: PPG 1.83 - 70 point season.
To hit 90 points, which will probably win the league the 3 teams need the following:
Us: 2.27 PPG which is 86 points season form.
City 2.58 - 98 point season form.
A*** 2.62 - 99 point season form
Based on 90 winning it we can drop 19 points and still get 90, that's nearly a quarter of the remaining points. City can only drop 11 and Arsenal 10 to get 90.
It's looking good!
