Previously we looked at some data from last season and tried to set a rough benchmark as to how much value you need from premium defenders in order to be worth their higher price tag. If you didn't catch that piece then I'd encourage you to do so, but if not, the TL;DR is that we estimated that you should be aiming to earn somewhere around 26 points attacking points (goals, assists and bonus points) for every 1.0m extra invested over a player in the same team i.e. Alonso over Luiz or Walker over Stones. It's also worth re-empahasising that this would exclude any playing time concerns, which further complicate things somewhat. The below graphic starts to plot the defenders from each team to quickly highlight the potential areas where the more expensive players are starting to show their value. I must note here that two gameweeks is too soon to draw any strong conclusions based on the underlying stats, but then again, we need to start making transfer decisions now so like i...

At this stage of the season, those of us who are statistically inclined face a bit of a dilemma. We know that too much weight should not be placed on the limited data that's available, but yet the alternative is to rely on no data and simply make your picks based on the one or two games of action you've seen, or worse, some voodoo about world class players not being able to score in August. With this in mind, this time of year offers a good opportunity to explore a couple of other broader topics before the games start coming thick and fast and we get lost in expected goal regressions. Though data in a wider sense may not yet be stable , we can start to take some reasonable confidence from starting lineups and some of the lessons we can draw from there. Specifically here, I am interested in (a) which players offer a discount among their teammates and (b) when would we be willing to pay for the more expensive option. This is typically most useful when it comes to defenders an...
