Billy Davies has been re-appointed Nottingham Forest manager.
The 48-year-old Scot was sacked in June 2011 but will return to the City Ground following Alex McLeish's departure on Monday.
"I'm delighted to welcome Billy back to our club and really look forward to working closely with him," chairman Fawaz Al Hasawi told the Championship club's official website.
"Billy has unfinished business with the Reds and we know how hungry he is for success. In returning to the City Ground we believe his leadership will help us fulfil our ambition of making it to the Premier League.
"Billy is a Forest legend who needs no introduction to our loyal fans. We know how excited he is to pick up where he left off last time and we will back him 110 per cent - this is a very exciting appointment for us."
Davies becomes the fourth Forest manager to work under the Al Hasawi family since they took over Forest in July.
Steve Cotterill was sacked within two days of their arrival and Sean O'Driscoll was also fired on Boxing Day, leading to the arrival of McLeish a day later.
Forest's next match is at Bristol City, now managed by O'Driscoll, on Saturday at Ashton Gate.
