Mowbray has now been in charge of Rovers for four years, but the club looks as though they will miss out on promotion once again.
And the Scotsman wants to know if the club's Indian owners, the Venky's, are willing to invest enough money to get the former Premier League stalwart back into the top-flight.
"Where are we? I think we're further on that when we came. I think we have got a lot more assets at the football club, we've got a much younger team that we don't want to sell on, but if the market came that we could sell, we have some assets," Mowbray said, via the Lancashire Telegraph.
"Sometimes you have to sell to improve, to move on and get better and let's wait and see what this club decide it wants to do and what the bigger picture for the club is.
"If the ambition is to get out of this league and get to the Premier League, at whatever stage, it has to have a plan to do that, and my belief is good recruitment, developing your own Academy players, having an identity and structure to the way you play and you have to develop over a period of time.
"Then hopefully you get the results you want over a period of time."
