Rangers have appointed Barry Ferguson interim manager until the end of this season.
Former captain Ferguson, 47, from Hamilton, takes over from Philippe Clement, with coaches Issame Charai, Neil McCann, Billy Dodds and Allan McGregor.
Clement was sacked on Sunday following a 2-0 Ibrox defeat against St Mirren, and leaves alongside Alex Rae, Colin Stewart and Stephan van der Hayden.
Brian Gilmour will continue with the club “to bridge the gap between the academy and the first team” according to a statement issued by Rangers.
Midfielder Ferguson had two spells at the club, from 1997 to 2003 and 2005 to 2009, and was boss at Blackpool, Clyde, Kelty Hearts and Alloa.
Rangers are second in the Premiership, 13 points behind Celtic.
Rangers CEO Patrick Stewart said: “Philippe and his team have worked tirelessly during their time at the club and ha e played an important role in developing the first team’s young players.
“I want to reiterate, the issues we are facing run deeper than the manager. The ongoing football review seeks to address those issues, and we will continue to implement its findings in the coming weeks and months, ahead of appointing a new manager.
“I was clear that everyone is judged on results, and nobody will get unlimited time in any role at the club.
“Ultimately, the team’s response following their early exit from the Scottish Cup was a cause for deep concern, leading the board to conclude that action had to be taken now.
“I want to wish Philippe every success in the future. He is a fine man whom I have enjoyed working with in my short time here so far.
“I also want to welcome Barry back to the club. We appreciate him and his team stepping into the role at this difficult time.
“Myself, the board and the executive team will give them our full support for the rest of the campaign.”
