Gary Rowett turned down Nottingham Forest job
Nottingham Forest are without a manager after sacking Philippe Montanier last month, with Gary Brazil currently in temporary charge.
But Rowett, who was sacked by Birmingham last December, admitted he turned down Forest's approach as it would be "a very difficult job to get right" at the moment.
The Championship club, who sit just five points above the relegation zone, are currently up for sale.

"There's been a lot of speculation about Forest as a club in terms of takeovers and whatnot," he told Sky Sports.
"I think all I can really say with that is when you look at a club, you say 'firstly, is there a structure there and are there the tools there for you to go there and do your job properly as a manager?'
"From the outside I can't say that I know Forest are structured really well and it looks like there's been quite a lot of turbulence, quite a lot of inconsistency in the way they've done things with various managers.

"And I think that would be a very difficult job to get right right now. Although I think the caretaker manager Gary Brazil's doing a fantastic job.
"If that structure was to change, I think myself and any manager out there would see Forest as an unbelievable club to be a manager of.
"I think the issue for me at this moment in time is where they are.
"I know there's a lot of talk in changing that, but I think it would be a very difficult job to go and do what I want to do there, which of course would be to try to get them in the Premier League."
