1. Jurgen Klopp Borussia Dortmund
Klopp has certainly caught the eye on the European stage in recent years, guiding his dynamic Borussia Dortmund side to the Champions League final in 2012/13 off the back of the Bundesliga titles they won under him in each of the previous two seasons. The German is a charismatic, young coach and would surely prove a popular choice among United fans.
2. Louis van Gaal Holland
The Holland coach has a vast amount of top-level experience and success on his CV, having previously been in charge of German giants Bayern Munich, Spanish heavyweights Barcelona and Dutch club Ajax. Van Gaal, who will quit the Holland team after the FIFA World Cup, has been heavily linked with both United and Tottenham of late.
3. Diego Simeone Atletico Madrid
Another youthful coach who has rapidly risen to prominence over the past few seasons, former Argentina international Simeone led Atletico Madrid to the Europa League title in 2012 and has overseen their run to the Champions League semi-finals this campaign, while they are also currently leading the Primera Division ahead of Barcelona and Real Madrid.
4. Laurent Blanc PSG
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.
5. Ryan Giggs Interim Man United coach
There are few players as revered among the Old Trafford faithful as the 40-year-old, who is already part of the current United coaching staff on top of being a squad member. There would be considerable goodwill towards him from fans if he were to land the top job, but he lacks management experience. He has been appointed as interim manager until the end of the season.
6. Sir Alex Ferguson Utd director
The 72-year-old, 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. Red Devils fans would take comfort from the sight of their most successful boss in the dugout again.
