Steele has been working closely with David De Gea since the keeper's arrival from Atletico Madrid in 2011, and has been credited with playing a big part in the 22-year-old's development and upturn in form during the 2012-13 campaign.
The former Manchester City and Blackburn coach had learned Spanish to better communicate with De Gea in training, and was in charge of an intense programme to bulk up the young shot-stopper.
Sir Alex made clear that he could not guarantee any member of staff a future at United when he announced his decision to leave the club at the beginning of May.
David Moyes, who has begun work at Carrington ahead of his official start date on July 1, will bring in his own men for certain positions, with members of his backroom staff at Everton expecting to join him in Manchester.
But Moyes has retained United's interest in Barcelona midfielder Thiago Alcantara, although the Premier League champions face competition from Manchester City.
