Former Blades midfielder Stuart McCall has been named manager of Rangers until the end of the season.
McCall has taken control of the crisis-hit club as they push for promotion through the Scottish Championship play-offs.
Kenny McDowall was in interim charge of Rangers following the resignation of manager Ally McCoist, who is on gardening leave until the end of the season.
But McDowall has also handed in his notice and remained until a new manager is appointed.
McDowall is expected to be named as assistant to McCall, who spent seven years as a player at Ibrox.
McCall made 71 appearances for the Blades between 2002 and 2005 as well as coaching the club’s reserves.
He departed following the Blades’ relegation from the Premier League when he was overlooked to succeed Neil Warnock in favour of Bryan Robson. McCall was named boss of Bradford City – whom he played with as the Bantams won promotion and subsequently survived in the Premier League – in June 2007.
He also managed Motherwell, guiding them to second in the Scottish Premier League and European football.
