The David Moyes era is over at Old Trafford, and United will now spend the next few weeks and possibly months trying to find his successor. The Red Devils are currently in seventh place in the Premier League just a year after winning the title, so the new manager will have a big task on his hands.
The bookmakers have been busy this week pricing up them managers in contention, so here is the daily look at who is moving in the market.
Interim boss Ryan Giggs has seen his odds slashed throughout the day, now coming in at a shortest price of 14/1 to replace Moyes. The fans would be well behind a player who has spent his entire career at Old Trafford, and all but one year of it under Sir Alex Ferguson, but his inexperience makes him a risky candidate.
But the biggest mover of the day is Juventus boss Antonio Conte. The Italian is on the verge of winning his third consecutive Serie A title in Turin, and has been backed into as short as 19/1 today, making him the sixth favourite to take the reins at United. Having represented Juve in his playing days, it might take some convincing to prise him away, but he certainly has a growing reputation in Europe.
There wasn't a great deal of activity at the top end of the market, but former United assistant Carlos Quieroz has really drifted out, now as long as 61/1 to be appointed. Currently manager of Iran ahead of the World Cup in Brazil this summer, Queiroz has had disappointing spells in charge of Real Madrid and Portugal which would seemingly scare United off a move for Ferguson's former right hand man.
Another manager who has seen his odds lengthen is Bayern Munich's Pep Guardiola, but that always seemed like a pipe dream. The former Barcelona man watched on as his Bayern side were beaten 1-0 by Real Madrid in the Champions League last night, and with a longest price of 50/1, it seems he is out of the running.
For the third day in a row, Holland boss Louis van Gaal remains the odds-on favourite to take over at Old Trafford. Having already announced that he will leave his post after the World Cup and return to club football, the 62-year-old has the reputation and experience that United are seeking and the bookmakers seem convinced that the former Ajax, Bayern Munich and Barcelona coach will be the new man at the helm for United.
