David Moyes' reign as Manchester United manager has come to an end, sacked less than one season into the job.
Among the early runners and riders according to BetVictor are the current Netherlands manager, and even a current player.
Louis Van Gaal: 9/4 favourite
Louis van Gaal is a Dutch football manager who is current manager of the Dutch national team. Formerly coach for Ajax, Barcelona, AZ and Bayern Munich he has won multiple trophies at all the clubs he has managed.
He has a good relationship with Manchester United player Robin Van Persie who plays for the Netherlands national team under van Gaal.
Jurgen Klopp: 5/1
Current manager of Borussia Dortmund he has won the Bundesliga in 2011 and 2012, the DFB-Pokal in 2012 along with two Supercups.
Klopp has also won the German Football Manager of the Year award in 2011 and 2012.
He also wrote his sports science diploma thesis about walking and once compared his managerial style to "heavy metal music".
Ryan Giggs: 5/1
Giggs has no managerial experience, yet he has played for the club for over 24 years, won numerous trophies and worked on gaining his coaching badges.
Ryan Giggs will be named as interim manager of Manchester United later today, Press Association Sport understands.
Diego Simeone: 14/1
Argentine former football player and current manager of Spanish La Liga club Atlético de Madrid, Simeone won the UEFA Europa League with Atlético Madrid, the UEFA Super Cup, Copa del Rey and led the team to a 3rd place finish in 2012-13 La Liga, the club's best finish in the competition since 1996.
Sir Alex Ferguson: 18/1
The 72-year-old Scot, who has stayed on at the club as a director since finishing as manager, returning to the hot seat so soon after selecting Moyes to be his successor would certainly be interesting.
Whether Ferguson would even entertain the idea is very much up for debate, as is the issue of what his comeback would mean for United in the long-term, given the age-old question of 'how do you replace Fergie?' would be straight back on the agenda. Red Devils fans would take considerable comfort from the sight of their most successful boss in the dugout again, though.
Laurent Blanc: 16/1
Blanc won the Ligue 1 title as Bordeaux coach and looks set to secure it again this term with Paris St Germain, having had a stint in charge of the France national team in between.
The fact that he spent time at Manchester United at the end of his playing career would likely count in his favour in terms of how he would be perceived by the club's supporters.
All odds are subject to change.
