However, all good things must come to an end and after three years at Old Trafford Robin van Persie has agreed to sign for Turkish outfit Fenerbahce in Istanbul.
After eight years at Arsenal in which he only won the FA Cup van Persie was brought to United by Alex Ferguson for a fee of around £23m and immediately made an impact with the United faithful by choosing to wear the number 20 on his shirt explaining that if the Red Devils win the Premier league in his first season it would be their 20th.
At Arsenal van Persie had regularly been sidelined with injuries, but in his first season at United it was a different story as he went on to make a total of 48 appearances scoring 30 goals a brilliant return by any standards.
Sadly for United and as it turned out van Persie, Alex Ferguson called it a day while he was at the top and was replaced in the summer of 2013 with David Moyes. Things did get off to a promising start as van Persie scored a double against Wigan in the traditional curtain opener, The Community Shield, and he carried his goal scoring form into the first league match of the season scoring another two against Swansea City on the road.
However, the season turned out to be a disaster for the club with the players clearly not enjoying the style of play under Moyes. Over the season van Persie managed 28 appearances and scored 18 goals.
The celebrations were hampered by the news that United's goal hero had picked up an injury that would mean he would not only miss the quarter-final against Bayern Munich, but also meant that he would not be available for selection by interim manager Ryan Giggs, who had replaced sacked Moyes, until the season was all but over.
Van Gaal and his team managed to go all the way to the semi-finals and United fans became excited about the upcoming season, especially with the new talent brought into the squad which would include a potent forward line of van Persie, Rooney, Falcao and Di Maria. To say the fans were licking their lips would have been an understatement.
Van Persie was overlooked by van Gaal for the captaincy of United in favour of Rooney at the start of the 2014-15 season, but as the gentleman he is van Persie never moaned and gave his backing to his new captain.
Over the season van Persie managed to make one more appearance than the previous one, but it was his eye for goal that was the problem managing only 10 which all came in the league. To be fair, he did miss a chunk of the season with an ankle injury and at the age of 31 his stamina must have been sapped by a long run and the heat in the World Cup in Brazil.
Even though United qualified for the Champions League by finishing fourth it became clear that van Persie wasn't in van Gaal's plans for the future and a move to Fenerbahce was agreed.
If only he had joined at a younger age who knows what more he could have achieved as a Red Devil.
Good luck and thanks for the great memories and goals Robin.
