Bolton manager Sam Allardyce has been told he has to take a pay cut as the club seeks to reduce its debts.
Allardyce became manager in 1999
The Trotters parent company, Burnden Leisure, have debts of about £38m and the wage bill rose from £5.2m to £21.7m during the last financial year.
"The manager's been told he might have to take a pay cut," assistant manager Phil Brown told BBC GMR.
"If we have to do some wheeling and dealing in the transfer window we will but there won't be any major coups."
Brown added: "There's an awful lot of financial constraints going on at the club at the moment. "
Allardyce took over at Bolton in 1999 and guided the club to the Premiership, where they have been since beating Preston in the 2001 play-off final.
