Bolton have parted company with manager Sammy Lee by mutual consent.
Lee was promoted from assistant manager in April 2007 after the departure of former manager Sam Allardyce.
But he has had a difficult start to the current campaign as Bolton lie second from bottom of the Premier League with just one win from their opening nine matches.
Frank McParland was general manager at Bolton and he has also left the club
“This has been a difficult decision for all parties but we have agreed the time is right,” Bolton chairman Phil Gartside told the club’s website.
“Sammy has played an important role in the club’s recent history. We wish Sammy and Frank well for the future.
“Our efforts will now be to look for a replacement manager to concentrate on the future.”
It has been reported in recent few weeks that several senior members of Bolton’s squad were unhappy with Lee’s managerial style, with Gary Speed and Kevin Nolan both dropped from his starting XI for recent games.
Speed was also ‘relieved’ of his coaching details last week, prompting speculation of a rift between the pair.
Bolton have reached the group stages of the Uefa Cup and will face games against Bayern Munich, Red Star Belgrade, Aris Thessaloniki and SC Braga if they hope to progress to the knockout stages.
