Keane is keen to bring in Miller on loan and West Brom is reportedly prepared to let the striker leave.
“Ishmael Miller will have plenty of options,” said Keane.
“We are in the market and if you think we are the only club in for a player like him then you are mad.
“He is a good player and good players are always in my thoughts. I don’t think we’d be the first option for players from Premier League clubs in the Midlands or the North West.
“We have trouble attracting players down here as they don’t often want to move away so we may have to look at younger players.”
