EPL 2021/22 season is over, and for many Fantasy Premier League managers now there is a time to recap and evaluate their season.
As clean sheet odds and expected clean sheets are an important part of our decision-making process when selecting defenders for our FPL team, let’s look at which teams kept the most clean sheets in the 2021/22 season and which teams and which teams over or underperformed their defensive expectations based on bookies odds.
Just a quick reminder, before every gameweek of the 2021/22 season we calculated clean sheet odds (probability of keeping a clean sheet) for all Premier League teams using our Odds to probability calculator.
That helped us to construct an expected clean sheet table – a table with an expected clean sheet count for each team. This table shows how many clean sheets each team should have kept in comparison with the actual clean sheet count.
So, when we make difference between the actual and expected clean sheets, we get delta: the number which shows whether a certain team over/underperformed its defensive expectations according to boookies odds.
