Chelsea paid out more than £75m to football agents and intermediaries over the 12-month period to February 2024, as Premier League clubs spent a combined £409.5m.
Manchester City's outlay on agent fees exceeded £60m, according to figures released by the Football Association detailing payments made by Premier League, EFL and National League clubs.
The figures may also include transactions which clubs entered into before the start of the reporting period in February 2023.
Chelsea (£75.1m) and Manchester City (£60.6m) far outspent their Premier League rivals, with Manchester United the third-highest spenders (£34m) - having paid less than half of Chelsea's total.
