Newcastle United have confirmed that manager Glenn Roeder has resigned and the northern England club has started the search for his successor on Monday.
Roeder, former West Ham United manager, ended his 15 months in charge of the Magpies on Sunday, the day after a 2-0 loss to Blackburn Rovers at St James' Park, but there was no official confirmation until the following day.
"Newcastle United today announced that Glenn Roeder has offered his resignation as team manager with immediate effect and this has been accepted by the Newcastle United board," a statement issued through the club's website said.
The loss to Blackburn left Newcastle floundering in 13th position in the Premiership having not scored a goal at home for over eight hours, their worst run since 1951.
Speculation has been rife that Roeder will be succeeded by former Bolton manager Sam Allardyce who turned down the Newcastle job before Graeme Souness, Roeder's predecessor, was offered it in 2004.
Allardyce surprisingly resigned as Bolton boss last week after seven-and-a-half years at the helm amid other rumours he could be appointed manager of Manchester City in the summer.
Newcastle did not immediately announce who would take charge of the team for Sunday's final Premiership fixture at Watford, but at least one bookmaker has stopped taking bets on Allardyce getting the eventual permanent job.
Anger from fans
Roeder, 51, was desperate for time to turn things around for Newcastle after a mid-season injury crisis, but his position was on shaky ground when fans turned on him for the first time after Saturday's loss.
Much of the supporters' anger, however, was directed at Newcastle chairman Freddy Shepherd, who has fought off two takeover bids in recent months, and now faces the task of appointing a fifth manager in less than ten years.
While Allardyce is now available, he still has two and a half years remaining on his Bolton contract which would mean a sizeable compensation payment that Newcastle could do without after having to pay out similar costs after the departures of Souness and his backroom staff.
Whoever replaces Roeder's will inherit a squad which is full of talent on paper at least, but has a dismal capacity for under-achievement and is in serious need of a radical overhaul.
