Mick McCarthy has emerged as an early front-runner to replace Owen Coyle at Bolton.
The former Wolves manager, out of work since leaving Molineux in February, is an even-money favourite with Sky Bet.
And there has been money in support of Ole Gunnar Solskjaer, who is on course to win back-to-back Norwegian titles with Molde.
Solskjaer, who turned down the opportunity to speak to Aston Villa in the summer, has also been linked with the vacancy at Blackburn.
Coyle lost his job after overseeing just three wins in 10 Championship games this season, but the Scot reckons his successor will have all the tools in place to push for an immediate return to the Premier League.
He said: "I certainly believe we would have got promotion this season from the position we're in.
"Ultimately the people who make the decisions want to seek a fresh face. But whoever that is they're coming into a marvellous opportunity at a wonderful club. "
