There's statistics and then there's ...
... statistics.
This is interesting momentarily but has
(i) no reference to other tournaments (cup competitions)
(ii) no link to the value-added that managers bring to the situation they inherit.
(iii) no appreciation of the resources at their disposal.
(iv) no reflection of length of time in role.
None of which observations would probably have helped PL's situation, but just saying, like.
