Angel di Maria has written an open letter to Manchester United fans following his move to Paris Saint-Germain.
In the letter, he thanked the fans for their support and apologised for his performances last season.
"I write this note to thank all the Manchester United family for the great support received during the year I've been part of this club," Di Maria wrote.
"When Manchester United chose me as part of their team, I felt extremely honoured because I knew what this club means and how it trusted me.
"Nevertheless, I'm aware things didn't work as we all expected and believe me, I feel really sorry about it.
"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!
"Wish you all the best in the world. With best regards, Angel di Maria."
Di Maria scored just three goals in 27 appearances last season.
