"It was difficult times for the football club, for the fans, for the staff," he told reporters. "We had staff members being made redundant and losing their jobs, but we had to really try and keep it close-knit. Sometimes through the most difficult moments bring people together, and I think that's exactly what happened."
Rooney added: "Derby County has a huge place in my heart. My last game in football was for Derby and they gave me an opportunity in management and I had some really good times there. The fans were excellent, so it's a place where I really enjoyed going into work. Of course while they're playing us I don't want them to do well, but other than that it's good to see them back in the Championship."
