Blackburn Rovers boss Steve Kean says they're working overtime to bring in new signings.
Rovers are yet to make a major transfer since the end of the season.
On the transfer hunt, Kean told the Lancashire Telegraph: "We are very busy at the moment.
"We haven't got anything solid at the moment but we have been busy over the last three to four weeks.
"I am sure we will have three or four signings by the start of the season."
