Rovers boss Tony Mowbray says it's important to keep building his squad bit by bit to keep up with the demands of the Championship.
It's been a good opening 17 games back in the Championship for Rovers, who sit just outside the play-off places in the second tier.
Mowbray tied down key pair Charlie Mulgrew and Elliott Bennett to long-term deals during the international break, and is eager to ensure further stars remain Rovers.
“We need to progress and if we have a desire to get promoted, we need that support mechanism behind the club. That support has been there throughout my time at the club," Mowbray told iFollow Rovers.
“But we’re fighting in a division with lots of big teams. I look at Derby County, Aston Villa, Middlesbrough, Leeds United, we’re fighting with all those clubs.
“We’re in negotiations with one or two others, identifying the building blocks to make us competitive in this league and hopefully the next level as well.
“My career history suggests you can have a very good team, but if you don’t build then you’ll see that good team go very quickly."
And the gaffer knows first hand what can happen if you fail to secure your main players.
“Teams want to take everybody’s best players and I saw that at my last club not too long ago," he added.
“At Coventry City we had James Maddison, Ryan Kent, Adam Armstrong, Jacob Murphy, John Fleck. None of those players are at the club anymore.
“When you have good players, you have to keep them together and secure them. We need players to lead the way as the new signings come into the building."
