Lets use 6 seasons of Premier League expected goals data and Tableau!

For a look at managerial style we can plot defensive efficiency (expected goals against/actual goals against) on one axis and attacking efficiency (actual goals for/expected goals for) on the other.

We can colour up each manager by his expected goal difference per game and check the sample size by, erm, sizing each manager up by the number of games managed in the Premier League.

Having tools like these to hand should be standard in Premier League boardrooms. Never should clubs be unprepared in these situations. The information isn;t restricted to the Premier League either. You could have your finger on the pulse of all major leagues. It’s a great way to help inform important decisions.
