Alan Curbishley has become the first English Premier League football manager to depart this season when he resigned as West Ham United's boss after less than two years at Upton Park.
Curbishley, who played for West Ham in the 1970s, succeeded Alan Pardew as coach in December 2006.
His resignation was accepted by the club's Icelandic owner Bjorgolfur Gudmundsson with a statement saying it was in the best interest of both parties.
Curbishley was widely reported to be on the brink of quitting following the sale of defender George McCartney to Sunderland which he claimed was done without his authorisation.
He also made it known he was upset about the sale of Anton Ferdinand to Sunderland last week.
West Ham have won two of their opening three Premier League games this season and have scored eight goals in their last two matches; a 4-1 win over Macclesfield Town in the League Cup and a 4-1 win over Blackburn Rovers in Curbishley's last match in charge on Saturday.
West Ham's next manager will be their fifth in the last seven years since Harry Redknapp left in 2001, a stark contrast to the six managers they had in an 88-year period from 1902 to 1990.
