Georgson told United's website: "It has been a fantastic experience, serving as first-team coach at Manchester United, and I will always be proud of my association with such a great football club. This period of my career has now come to an end, as I leave to find a new challenge elsewhere. While excited about the opportunities ahead, I am sad to be leaving so many great colleagues and friends at Carrington, who make Manchester United truly special.
"Even during such a tough season, the professionalism and dedication of the players and staff never wavered, and I know there will be better times ahead."
Technical director Jason Wilcox added: "Andreas has been a valued member of our men's first-team coaching set-up over the past year, and we are grateful for his significant contribution.
"He leaves with our thanks and best wishes for the next stage of his career."
