The German coach of Borussia Dortmund has been touted as one of the leading candidates to replace the sacked David Moyes
The Scot succeeded Sir Alex Ferguson but has now presided over the Red Devils' worst Premier League campaign, with the club set to miss out on Champions League football next season. That was just one of a series of negative records broken by Moyes and the board finally had enough, dismissing him less than a year into his six-year contract.
Player-coach and club legend Ryan Giggs was named interim manager shortly after, as speculation about the next man to take charge went into overdrive following the news.
Topping our poll of a five-man shortlist is Jurgen Klopp, with 52.8% of Goal Singapore readers indicating that the German was their preferred choice. However, the 46-year-old has insisted that he does not want the job, claiming an "unbreakable" bond to Borussia Dortmund.
Incidentally, Giggs was the next most popular choice, with 19.8% plumping for him, perhaps convinced by his stature at the club. Former team-mate and England coach Gary Neville did not fare so well, garnering 3.7% - the least.
Louis van Gaal, who has been widely tipped to take over, got 13.6% of the votes. The Dutchman has openly declared interest in the job, saying that he is "very keen". Atletico Madrid boss Diego Simeone came in with 10.3% of the votes, placing him fourth.
As expected, there are a host of other names being bandied about, with even Sir Alex Ferguson touted to make a comeback from retirement in some quarters.
It will be interesting to see who United appoint as the next manager and when they do it, with Giggs expected to see out the rest of the season.
