Derby County have confirmed the appointment of Rotherham manager Paul Warne as the club's new head coach with immediate effect.
The 49-year-old - who had been in charge of the Millers since November 2016 - has signed a deal that will run until the summer of 2026.
He takes over from Liam Rosenior, who had been in interim charge since Wayne Rooney left the League One club in the summer, but was relieved of his duties on Wednesday.
The Rams are seventh in League One, just outside the play-off places on goal difference, after picking up 14 points from the opening nine matches of the season.
Warne will be joined by his coaching staff members assistant head coach Richie Barker, first team coach Matt Hamshaw and first team goalkeeper coach Andy Warrington
He will oversee his first game in charge when the Rams head to Cambridge United in Sky Bet League One on Saturday October 1 and his first home match at Pride Park Stadium will be the meeting with Port Vale on Saturday October 8.
Upon the announcement of Warne's appointment, a Derby statement read: "As was made clear in the summer, the board intended to take a period of time evaluating every aspect of the club and having done that, we believe Paul's track record of success at this level fits perfectly into our long-term strategy.
