Shearer is one such former player, and he admitted that he could be interested in taking over but warned that things would have to change before he would consider it.
"It's a strange one at Blackburn, I'm sure they had a plan with Steve Kean but it's now a tough situation," Shearer told BBC Sport.
"Whoever takes over, they have to make sure it is the right choice. With my history at Blackburn, I would speak to them if they called me but I think things would have to change."
Shearer scored 130 goals in 171 appearances for Blackburn between 1992 and 1996.
