Louis van Gaal was officially confirmed as the next Manchester United boss on Monday afternoon to end one of the worst-kept secrets in football.
The Dutchman will take over at Old Trafford after this summer's World Cup, and the Oranje boss has elected to keep the Welsh legend on as his assistant boss.
The legendary Giggs expressed his eagerness to learn his trade under the esteemed Van Gaal in a statement after the announcement of the 62-year-old's appointment.
On manutd.com, he said, "I’m thrilled to have the chance to serve as assistant manager, Louis van Gaal is a world-class coach and I know I’ll learn a lot about coaching and being able to observe and contribute from such close quarters.
"Manchester United has been a huge part of my life and I’m delighted to be able to continue that relationship in such a key role.
Chief executive Edward Woodward told the club's official website: “I’m delighted that Louis has chosen Ryan as his assistant, Ryan’s association with the club spans over two decades and his knowledge and stature will be of great use to Louis.
“In addition, this is a fantastic opportunity for Ryan learn his trade alongside a world-class manager whose attacking instincts and belief in youth are tailor-made for Manchester United."
Giggs ends his 24-year playing career with 35 winners' medals, which includes 13 Premier League titles, four FA and League Cup triumphs and two Champions League trophies.
In an open letter to the United fans, the 40-year-old said, "I would also like to take this opportunity to announce my retirement from professional football and embark upon a new and exciting chapter in my life, as assistant manager of Manchester United.
"I am immensely proud, honoured and fortunate to have represented the biggest club in the world 963 times and Wales 64 times.
"My dream was always to play for Manchester United, and although it saddens me to know I won’t be pulling on a United jersey again as a player, I have been lucky enough to have fulfilled that dream playing with some of the best players in the world, working under an incredible manager in Sir Alex Ferguson, and most of all, playing for the greatest fans in world football.
"I have always felt and appreciated your support."
Giggs, who made his United debut in 1991, took charge of the final four games as interim manager following David Moyes' sacking.
