Manchester United have confirmed the appointment of David Moyes as their new manager on a six-year contract.
The 50-year-old will take charge at Old Trafford on July 1 after completing the season with Everton.
Moyes said: "It's a great honour to be asked to be the next manager of Manchester United.
"I am delighted that Sir Alex saw fit to recommend me for the job. I have great respect for everything he has done and for the football club.
"I know how hard it will be to follow the best manager ever, but the opportunity to manage Manchester United isn't something that comes around very often and I'm really looking forward to taking up the post next season.
"I have had a terrific job at Everton, with a tremendous chairman and board of directors and a great set of players.
"Between now and the end of the season, I will do everything in my power to make sure we finish as high as possible in the table.
"Everton's fantastic fans have played a big part in making my years at Goodison so enjoyable and I thank them wholeheartedly for the support they have given me and the players.
"Everton will be close to me for the rest of my life."
Outgoing boss Sir Alex Ferguson said: "When we discussed the candidates that we felt had the right attributes, we unanimously agreed on David Moyes. David is a man of great integrity with a strong work ethic.
"I've admired his work for a long time and approached him as far back as 1998 to discuss the position of assistant manager here.
"He was a young man then at the start of his career and has since gone on to do a magnificent job at Everton.
"There is no question he has all the qualities we expect of a manager at this club."
