The last time we talked about Footbalomics (or the analysis of football data) we discussed a marked disparity in the performance of a certain Premier League club (Liverpool FC) in dealing with top competitors as opposed to lesser opponents. In that post we saw that LFC were doing remarkably well against better teams, while the norm is that most of the clubs do better when playing inferior teams (as expected) and a few do equally well against all (PL leaders Chelsea is a notable example).
