Measuring chemistry: Are Leicester a statistical anomaly?

Since the end of November, Leicester City have never slipped lower than second in the Premier League table and still, for so much of the campaign, many have expected an inevitable collapse.
Now, with eight games to go, they’re five points clear at the top. In some quarters, the club’s inexplicable turnaround from relegation candidates to title favourites has been treated as nothing more than a novelty but such an attitude belies the fact that Leicester have succeeded where so many high-profile and experienced teams have failed.
