Squad churn, 28 July 2021

As is usual over the summer, I’ve been tracking how much each Premier League and EFL squad has changed since last season. It’s been three weeks since the first version, so I felt like it was worth an update.

I’ve harvested the data from the official retained lists, the BBC transfer page, Transfermarkt and a variety of Twitter sources, so hopefully I haven’t missed anything. You can see the all the data I’ve compiled in a Google Sheet here – please let me know via Twitter if you think I’ve gotten anything wrong.


There’s a brief explanation of how these work at the top of each graphic, but in summary I’ve plotted a donut chart for each club where every player’s league minutes from last season is a separate segment, ordered from largest to smallest. I’ve then shaded them dark if they’re still at the club and light if they’ve left, so you can see at a glance how regularly departing players featured last season.

There’s still plenty of time before the transfer window shuts, so I’ll look to update these once there have been enough changes (and I’ll keep the Google Sheet up-to-date in the meantime).
