Keith Hill has returned for a second spell as League Two Rochdale manager, replacing John Coleman, who was sacked on Monday, reports BBC Sport.
The 43-year-old is back at Spotland just 19 months after leaving the club to become boss of Barnsley.
Hill, who has agreed a deal until the end of the season, told the club website: "When the club approached me about coming back to Spotland, I didn't hesitate.
"Rochdale Football Club will, and always will remain dear to me, and to be honest it was a no-brainer.
"I'll be here until the end of the season and we will take stock of the situation then.
"Until then, we have an 18-game season to think about, to plan and to achieve so that's what I, the players and staff will be doing.
"We also need the fans to get behind us and give us all their support. That is crucial if we are going to go forward. I'm delighted to be back and cannot wait to get started."
Chairman Chris Dunphy added: "This is not a position we, as a club, would have liked to have found ourselves in, but after a recent run of poor form it was important that we acted now.
"I am delighted that Keith has decided to take the job and I am confident in his experience and his ability to work and develop our current squad."
