Paris Saint-Germain winger Angel Di Maria has apologised to the Manchester United fans for his disappointing campaign at Old Trafford last season.
The 27-year-old was a £59.7m signing from Real Madrid during last summer's transfer window.
But he struggled to make an impact in Louis van Gaal's squad, making a move to Paris Saint-Germain for a reported fee of £44.3m.
"I'm aware things didn't work as we all expected and believe me, I feel really sorry about it," Di Maria wrote.
"However in the career of a football player sometimes the unexpected and unwanted may happen. I can guarantee you it was not for trying.
"I did my best but football is not like maths: often a lot of things out of our control affect the way we feel and the way things turn out. I am sorry it did not work out as I would have wished in this amazing huge club.
"I want to give special thanks to all the directors and management of Manchester United as well as to every member of the staff and colleagues as they gave me all their support.
"Also a special mention to all the fans who always trusted me and showed me their respect and love. Now is time to move to PSG but the Glorious Manchester United Club will be forever in my memory!"
