With the repercussions of last Saturday's defeat still ringing through the halls of Old Trafford and reports suggesting Louis van Gaal is ready to quit, football fans will be wondering what on earth has happened to England's 20-time league champions.
When Sir Alex Ferguson left Manchester United in 2013, all that was needed was some fresh blood to take on the mantle and re-focus efforts on developing youth.
But alas, this has yet to materialise and United have instead opted for European talent.

What Ferguson did was purchase solid, experienced squad players and build a team around the rich foundation of talent already at the club - the rest is history.
The Scot also instilled an attitude within the team of winning at all costs - an ethos currently bereft at the Theatre of Dreams.
The negative style of play now implemented at Old Trafford also appears to be having a profound effect. Gone are the days where the Red Devils would go toe-to-toe with their opponents and overpower them using a mixture of exciting and explosive football.
Whether Van Gaal decides to stay or leave, United must make three fundamental changes to transform their fortunes.
The first is to focus on purchasing experience over youth. For all the up-and-coming European talent at Old Trafford, United lack players of authority and presence who play on a regular basis.
Wayne Rooney and Chris Smalling are two of such authoritative players, but without regular game time, the likes of Bastian Schweinsteiger and Michael Carrick are unable to influence.
The Red Devils must also adopt a tougher attitude. Ferguson's teams thrived from knowing they could outscore each and every opponent faced - and Van Gaal's crop of stars must also start believing they can too.
And finally, the club's hierarchy must seek to repair what was once a world-renowned youth academy. No longer is Europe's best, fresh talent being churned out at Carrington, which is considerably impacting the club's future prospects.
