"Yes, David Dunn is one we are looking at," Bruce told the Lancashire Evening Post.
"He fits the bill in that he's a talented and exciting player and he's young, too, which is typical of what we want.
"I'm a great admirer of his and we have made an enquiry about him."
If Bruce manages to persuade Rovers to part with Dunn it would smash the current £4.5 million transfer record that the Blues boss paid Crystal Palace for striker Clinton Morrison last summer.
