Wayne Rooney will join Derby as a player-coach from January, the Championship side have announced.
The 33-year-old former England international has signed an 18-month contract and will switch to the Pride Park side after he sees out the remainder of the 2019 Major League Soccer season with DC United.
Derby boss Phillip Cocu told the club's official website: "Wayne Rooney is an extremely talented and top-class footballer.
"It is an exciting prospect for him to be joining Derby County and he can bring so much to this squad, both on and off the pitch.
"He has enjoyed a wonderful career, both in club football and for England, and he still has so much to give as well."
Rooney is excited by his new dual role, but remains focused on DC United's play-off push before his return to England.
"I am very excited about the opportunity that Derby County have provided me with," Rooney said.
"I am looking forward to joining Phillip Cocu, his coaching staff and the first-team squad from the start of January. I am sure I can make a big contribution and can't wait to meet everyone, especially the supporters.
"I am equally excited to begin my coaching career at Derby County working with both the first team and academy.
"I must also take this opportunity to thank DC United, their owners, executives and supporters who have been superb to work with. I want them to know that I will give my all in support of our push for the play-offs."
Derby boss Cocu added: "His credentials speak for themselves. But to have a player with his leadership, skill, experience, character and work ethic will be huge for us. He knows what it takes to succeed as a player and I have no doubt he will have a positive impact right across the club.
"The inspiration and motivation this can generate is massive for all of our players, from the first team right through to the youngsters in the academy. It is entirely in keeping with, and in support of, the club's philosophy and approach.
"I am looking forward to working with Wayne from the start of next year and welcoming him to the club."
Golden Generation in the dugout
Here is a look at how Rooney's former international team-mates have performed on the sidelines so far.
Gary Neville
Better known as a television pundit since retiring as a player, Neville was already an assistant with England when he was surprisingly appointed Valencia manager in December 2015. He was sacked in March 2016 after 28 games which yielded 10 wins, seven draws and 11 defeats, including a 7-0 thrashing by Barcelona in the first leg of their Copa del Rey semi-final.
John Terry
Terry finished playing for Aston Villa after the club's defeat in the Championship play-off final in May 2018 and announced his retirement as a player in October. Just days later he was appointed as assistant to new Villa boss Dean Smith and the club gained promotion to the Premier League by beating Derby 1-0 in the play-off final in 2019.
David Beckham
Beckham has not gone directly into coaching but bought an MLS franchise in 2014 and Inter Miami are finally scheduled to begin competing in 2020 after delays over their stadium. Beckham is also a director of Salford City after joining former 'Class of 92' Manchester United team-mates Ryan Giggs, Nicky Butt, Paul Scholes, Gary Neville and Phil Neville in taking a 10 per cent share in the club.
Steven Gerrard
Former Liverpool captain Gerrard coached a number of the club's youth teams after hanging up his boots before signing a four-year deal to manage Scottish Premiership side Rangers. Gerrard's reign began with a 12-match unbeaten run in all competitions but fierce rivals Celtic won a third consecutive domestic treble as Rangers finished second in the league.
Frank Lampard
Lampard was appointed Derby manager in May 2018 and saw his side knock Manchester United out of the Carabao Cup at Old Trafford in his 12th game in charge. The Rams went on to finish sixth in the Championship and, after beating Leeds in the play-off semi-finals, lost to Aston Villa in the final at Wembley. Lampard signed a three-year contract as head coach of former club Chelsea in July.
Paul Scholes
Due to his stake in Salford City, Scholes needed permission from the English Football League to be appointed manager of League Two side Oldham in February 2019, signing an 18-month contract. However, he resigned after just 31 days in charge and one win from seven matches.
