Steve Bruce feels Birmingham have made a statement of intent by bringing in Stephen Kelly, Neil Danns and Cameron Jerome.
Blues are looking to bounce back to The Premiership at the first time of asking and Bruce has made wholesale changes at St Andrews.
The likes of Chris Sutton, Mario Melchiot and Stan Lazaridis were not offered new deals, while Nicky Butt's loan from Newcastle was not made permanent, and this afforded Bruce room to manoeuvre in the transfer market.
He has made three new signings and feels it hammers out a warning to the rest of The Championship.
"Because of letting nine players go, with the wages and all that, and the owners having got a few bob, we could do this," Bruce told Sky Sports News. "I think they wanted to make a statement.
"We don't want to be in this division again, we don't want to be here. We felt harshly treated last year, but whatever's gone has gone."
Bruce wants committed players at St Andrews, but will only sanction sales if he feels it is the right move for Birmingham.
"They are contracted to stay," he added. "I don't want to be in this division, the supporters don't want to be in this division, certainly the board don't and the players don't want to either.
"But we find ourselves here, we have to roll our sleeves up, get ourselves out of this division and put the club back where it belongs."
Birmingham are favourites to secure promotion, but Bruce does not expect life to be easy in The Championship.
"We have got to live up to that (being favourites) and make sure we don't think that we can stroll around," he stressed. "It is a tough division. We have six or seven derby games for a start."
