Derby County have re-appointed Steve McClaren 17-months after he was dismissed by the Championship club.
The Rams announced on Twitter that McClaren had signed a contract that will run until the end of the 2017/18 season.
The former England boss replaces Nigel Pearson, who left by mutual consent on Saturday after less than five months in the post.
Chris Powell, who was in temporary charge of the club has returned to his previous role of assistant manager at the iPro stadium.
Derby’s backroom staff remains strong with Kevin Phillips and Pascal Zuberbühler both keeping their roles as coaches.
McClaren who left Derby in 2015 for Newcastle United, has a rich history of clubs on his CV including FC Twente, VfL Wolfsburg and Nottingham Forest.
The 55-year-old was sacked from Newcastle United in March following a 3-1 home defeat to Bournemouth.
McClaren spoke to press about rejoining The Rams, saying “I have a great affiliation with the club, having been here on three previous occasions, and I am really delighted at the prospect of finishing what we started.”
Derby are currently 20th in the Championship, two points away from the relegation zone.
McClaren’s first game in charge will be against Leeds United at home this saturday.
