We have 73 points at present, GD+33.
In last 10 seasons, that would have been good enough, after 38 games to be:
15/16: - 2nd
14/15: - 4th
13/14: - 5th
12/13: - 5th on GD. 4th place had GD of +35
11/12: - 3rd
10/11: - 2nd
09/10: - 4th
08/09: - 4th
07/08: - 5th
06/07: - 3rd
So 70% of the time, our current points tally (even with a GD slightly worse than we have now, has been enough for top 4).
For what it's worth, in 2 of the 3 seasons in which 73 points was only hypothetically good enough for 5th, that year's LFC was one of the teams in the top 4 (2nd in 08/09 and 13/14 respectively).
In other words, in 9 out of the last 10 seasons, had LFC got 73 points, then they would have been in the top 4.
In the only other season (12/13), 73 points would have seen us lose out only on Goal Difference (to Arsenal).
Great effort so far. Fingers crossed for Sunday!!!
