Derby County chief executive Tom Glick says the club will sign two more strikers in the transfer window.
Frontman Nathan Tyson joined the Rams this week on a three-year contract after failing to agree a new deal with rivals Nottingham Forest.
Glick said: "Nathan Tyson's signing is another piece of the jigsaw.
"But we aren't finished yet and we expect to do two more pieces of business in the striking area during this transfer window."
Glick continued: "Hopefully both of these will be before pre-season training starts.
"Both would be permanent signings for the club, and while loans can be effective, we have identified two strikers who we want to sign as permanent additions.
"It is always good to have choices and options and there is no better area to have that than the striking department."
Derby have already been very active in the close season with three of their five siginings being strikers.
In addition to the arrival of Tyson, Jamie Ward and Theo Robinson made their loan moves permanent in May.
