Rovers boss Tony Mowbray says the summer transfer market is all about timing, with a month to go until deadline day.
The only move made by the boss so far this suummer has seen Stewart Downing arrive at Ewood Park on a free transfer from Middlesbrough last month.
And although he is keen to add more quality to his squad, Mowbray adds that nothing is imminent.
“We hope the signings will come. It’s difficult because of the numbers at time," the boss said after jetting back from the pre-season training camp in Austria.
“The numbers are bigger early in the summer and clubs can just pick a number out of the air for their players.
“It’s a fine balance between the buying club and the selling club.
“But we have to have plans in place where if you can’t get a player for a certain number, you have to move on.
“I think a little bit of that has happened this week, but we’re working hard behind the scenes," he added.
“I know it’s very frustrating for the supporters as they think nothing is happening, but conversations are going on, we’re asking questions, and we’re hopeful of being stronger this season.
“As the clock gets closer to the deadline, clubs panic, they need the money to get their targets and the price drops for a potential player that could head out of the door.
“When you haven’t got countless millions you do need to manage the money and the budget. We need to spend the money wisely and negotiate hard."
