Birmingham City have announced the appointment of Wayne Rooney as their new manager on a three-and-a-half year deal to replace John Eustace, who was sacked on Monday.
The former England skipper left DC United last week, and will be joined by former England team-mate Ashley Cole, currently England Under-21s assistant coach, and John O'Shea, the assistant coach of the Republic of Ireland, who will both maintain their international roles.
Carl Robinson and Pete Shuttleworth, who both worked with Rooney at DC United, also move to St Andrew's.
"I am absolutely delighted to be joining Birmingham City at such an exciting time. It is very clear that they have a plan and are committed to realising their ambition for the club," said the ex-Manchester United striker.
"We are fully aligned on what is expected. I have been building my managerial career, putting myself in challenging environments, to get me ready for this opportunity. It's a project that gives me a sense of purpose and I can't wait to get started.
"We have some exciting young players in the squad, and some who are still to break through into the First Team, alongside a core of experienced senior professionals.
"I have a clear way that I want the team to play, and my coaching staff and I will work hard to implement it. We will create a winning culture here with an identity that gets Blues fans on their feet."
US-based Shelby Companies Limited completed a takeover of Birmingham in July and owner Tom Wagner has been reportedly seeking to make a change of management, with Rooney's name linked with the club in September.
In August, seven-time Super Bowl champion Tom Brady became a minority owner in the club.
Eustace was sacked on Monday despite guiding Birmingham to sixth place in the Championship this season.
He replaced Lee Bowyer in July 2022 and helped Birmingham finish nine points above the drop zone in the second tier amid off-field issues surrounding the ownership of the club.
Birmingham co-owner and chairman Wagner said: "Wayne is a born winner. We believe, with the support of his coaching staff, the club, and our supporters, he will take Blues forward on the next stage of our journey.
"His playing philosophy will help to realise the ambitions we have set for Birmingham City.
"Wayne has been preparing for an opportunity like this since he embarked on his coaching education whilst still a player at Manchester United. He and his staff have the full support of the board and everyone at the football club."
Rooney was relegated with Derby in 2022, having battled a 21-point deduction for entering administration and breaching EFL accounting rules.
He quit soon after and joined DC United in July 2022, leaving last week after failing to reach the MLS play-offs.
Birmingham chief executive Garry Cook said: "We are incredibly excited by Wayne's arrival. When the opportunity presents itself to appoint a manager who shares your ambition and is both a student and a great of the game, then you act. This is what we have done.
"We are confident that his appointment, supported by his hand-picked coaching staff, will culminate in a young, attack-minded team that will excite our fans.
"The timing of the appointment will allow Wayne to evaluate the playing staff and work with Craig Gardner (sporting director) on the squad's recruitment needs ahead of the January and Summer transfer windows. This is a defining moment for the club."
