David Moyes will succeed Sir Alex Ferguson as Manchester United manager on a six-year deal starting on 1 July.
Moyes, who leaves Everton after 11 years in charge at Goodison Park, was Ferguson’s recommendation to succeed him as manager at Old Trafford.
The 50-year-old was out of contract at Everton at the end of the season.
“We unanimously agreed on David Moyes,” said Ferguson, who announced his retirement on Wednesday after 26 years as United boss.
“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.
“There is no question he has all the qualities we expect of a manager at this club.”
Moyes, who was recommended to the United board by Ferguson and will be introduced as Red Devils boss in “due course”, said it was “a great honour” to be appointed as the new manager of the Premier League champions.
“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,” added the Scot.
