I did this for the Premiership (link) and I think it’s a pretty cool way to encompass and present a lot of data. I never really planned to look at leagues outside of England but it turns out I can put together bubble plots pretty quickly. So for La Liga:
A quick explanation:
x-axis: PDO. Further right = more luck
y-axis: TSR. Higher = better team
Bubble size: Points. More points = bigger bubble
Bubble shade: Goal difference. Green = positive, red = negative. Lighter shade = further from 0
Unsurprisingly Barcelona and Real Madrid are the best teams by a large margin. Barca had the edge this year, Madrid had a few more bounces go their way. Next years title is pretty much a coin toss from this point of view.
Levante aren’t very good. They’re big candidates for a drop off next year. If they make it to the Europa League group stages I imagine that will be one of the reasons given.
Villarreal were unlucky to go down. They weren’t very good but any one of the group of teams between 0.350 and 0.500 could have taken their place.
In terms of stats the spread of team TSR is similar to that in the Premiership, with the standard deviation being 0.08 in both cases. There’s a much wider spread of PDO in La Liga though (stdev of 75 vs 50 in the Premiership).
These are quite fun. Are there any other leagues people would like to see?
