If you judge a football club's efficiency by the extent to which it over-performs or under-performs given its resources, then the best run club in the Premier League, Brighton, visit the worst-run club, Chelsea, in the Carabao Cup third round at Stamford Bridge this evening.
Chelsea have spent £1bn gross in the three transfer windows since Todd Boehly and partners completed their Chelsea takeover at the end of May last year. And the team's got worse.
In 2022-23 under Thomas Tuchel, and then Graham Potter, and then Bruno Saltor (briefly) and then Frank Lampard, Chelsea scored 38 goals in 38 league games, with only Wolves, Bournemouth, Everton and Southampton scoring fewer.
