It's been a rather disappointing season at Old Trafford, with the club failing to qualify for the Champions League for the second time in three seasons.
Shortcomings in the league ultimately ended up costing Louis van Gaal his job, ending the constant speculation that surrounded the club for the majority of the season.
The Manchester United board has acted quickly to ensure past mistakes aren't repeated with the appointment of Jose Mourinho.

Manchester United is a club accustomed to success, and everyone associated with the club will want to reclaim the Premier League trophy this season.
Well, here we look at three reasons why Manchester United could win the Premier League in Mourinho's debut season at Old Trafford.
Despite the recurring problems in attack, Manchester United's defence was pretty consistent throughout last season.
The Red Devils actually boasted the joint best defensive record in the league last season, conceding just 34 goals in 38 games.
In Chris Smalling and Luke Shaw, Manchester United have the foundation for a solid back line. The £30 million acquisition of Eric Bailly from Villarreal seems to be a great piece of business as he could be the perfect partner for Smalling at the heart of United's defence.
Mourinho is a coach renowned for building his teams around a good defensive structure, thus expect more of the same at Old Trafford next season.
One of the highlights of Van Gaal's final season at the club was the emergence of several young stars settling brilliantly at senior level .
Marcus Rashford is a prime example of the developing talent in Manchester United's academy, becoming the youngest player to represent England at the European Championships this summer.
Anthony Martial is another young forward who has gone from strength to strength as the season went on, scoring 17 goals in all competitions during his debut season at the club.
In addition to the two, United have the likes of Jesse Lingard, Adnan Janujaz, and Memphis Depay, who could all be unstoppable on their day.
Pace is key in the Premier League, and United's new breed of attackers gives the side a dynamism it lacked for the last couple of seasons.
There has been a lot of excitement surrounding Old Trafford ever since Manchester United confirmed the appointment of Jose Mourinho as their new manager, and rightly so.
The Portuguese is in the small bracket of superstar managers in the modern game, along with the likes of Pep Guardiola and Carlo Ancelotti.
The former Chelsea boss has been branded a 'serial winner', securing domestic league titles in four different countries across Europe.
With a 66% win ratio in the Premier League, Mourinho stands tall as one of the greatest managers the English game has ever seen. The Portuguese has won the Premier league title on three occasions with Chelsea, and will be ever so keen to get his hands on the trophy in the red of Manchester.
