He was fired by the United board for not achieving the aims of the club mainly the failure to qualify for Champions League football next season.
Van Gaal has departed without anybody being any the wiser on what exactly the Dutchman's philosophy was. All he has left is a legacy of tactical ineptitude that bemused the fans and left them frustrated.
Louis van Gaal came to United in 2014 saying all the right things, but ended his second season, saying all the wrong things. Of course, the fans' expectations are high we are talking about Manchester United after all but to say that we put too much expectation on the team is ridiculous, to say the least.
The Dutch coach arrived at the club with an impressive CV after many successful years in club football and at the helm of the Dutch national squad. However, in two full seasons his philosophy got us absolutely nowhere, in fact, in the league they even went one step backwards.
Out of those summer buys only Martial proved his full worth as was evident on his scoring debut against bitter rivals Liverpool. That scoring form continued throughout his debut season ending up United's leading scorer with 17. A total that sounds low until you consider that he spent the season out on the left wing.
Van Gaal, like a lot of the players, talked up a good game especially in his famous press conferences. But when it came to the important part they failed to deliver time and time again on the pitch. Ten defeats in a league season is simply unacceptable.
The biggest problem had to be the distinct lack of goals that cost us a top four place as we ended the season on equal points with Man City who enjoyed a far greater goal difference.
In total United scored only 49 goals in the Premier League, which is the lowest achieved by a United team since the 1989-90 season, 46. The top scorer in the league was Anthony Martial with 11. Therein lies the problem. For all the possession they enjoyed the main problem was the inability to put the ball in the back of the net especially when you consider Wayne Rooney scored the only hat-trick of the season in August against FC Club Brugge in the Champions League qualifier.
At Old Trafford, the visitors only managed to score 9 times. This was down mainly to the partnership of Smalling and Blind and of course the brilliant De Gea who rescued his team on countless occasions.
Playing players in different positions, also had the fans scratching their heads in disbelief and at times amusement. Young, a winger, as the main striker while Martial, a centre forward, was on the wing. Rooney was utilised more in the midfield where he had some decent games. But Paul Scholes he is not and his scoring ability was wasted there.
Some players were used sparingly during the season and others too much. Herrera often had to take a back seat to Felliani and Carrick looked off the pace at times.
It wasn't all doom and gloom. United did play well against the so called big teams, including a double over bitter rivals Liverpool, a tremendous performance against Arsenal at home, beating City at the Etihad and the 3-0 win at Goodison which was probably the best away performance of the season. And they ended the campaign with their 12th FA Cup win and their first silverware for three seasons.
The fact that Leicester City have been crowned Premier League champions shows that there has been a shift in power from the standard big four. It will be interesting to see how the Foxes fare next season along with West Ham, Spurs and Southampton who all brought a breath of fresh air to the league.
If there is any consolation in finishing fifth in the league it is that Chelsea and Liverpool will miss out completely on Europe after both had replaced their managers and still failed to deliver.
The terrible double leg fracture suffered by Luke Shaw early in the campaign was a major blow to the United defence, but it did signal the rise of the youngsters to be given a chance by van Gaal in the first team.
There is one thing that van Gaal can take from his two-year tenure and that is, he brought the youngsters through from the lower ranks and gave them their chances in the first team. However, it has to be said that was due mainly to necessity rather than choice. He had released Adnan Januzaj and James Wilson on loan before the new year and didn't make any cover signings during the January transfer window, so in effect he had no choice but to turn to the reserves and Under-18's academy players.
The first of those introduced to join by now regular and cup final hero Jesse Lingard was Cameron Borthwick-Jackson at full back then the likes of Love, Varela, Poole, Weir and the great young talent Fosu-Mensah also had opportunities presented to them due to many injuries in the defence. Marcos Rojo missed a huge chunk of the season after shoulder surgery and the same went for Antonio Valencia.
Two debut doubles in two matches against Midtjylland in the Europa League and Arsenal in the Premier League had the fans and media foaming at the mouth at this talented goal scorer who clearly wasn't daunted by the prospect of playing regularly for the first team.
The United reserves retained their League Champions crown which speaks volumes for the work that the coach Warren Joyce did to bring such a talented group of players together and become a feeder for the first team.
