MILLWALL spent more than twice as much on agents' fees in the 2011-12 season as they did in the previous year, figures have shown.
The Lions paid player representatives £422,000 in commission in the past twelve months, a rise from £172,000.
A report by the Football League shows boss Kenny Jackett made a total of 48 transactions – a figure composed of all new player registrations, contract renewals, cancelled contracts and loan deals.
Millwall were part of a divisional trend that saw Championship clubs commit to pay a total of £18,704,976 in agents' fees compared with £14,089,702 in 2010-11.
Football League chairman Greg Clarke said of the increase: "Almost a fifth of the overall figure was spent by one club alone [West Ham].
"Where such spending forms part of a sustainable business plan it shouldn't be of great concern.
"Supporters should be encouraged to see our clubs committing themselves to the new Financial Fair Play regulations that will take effect across all three divisions in the new season."
