Derby County manager Paul Clement expects to make "one or two more signings" before the transfer window closes on 1 September.
A double injury blow during the opening-day draw against Bolton saw Will Hughes ruled out for six months and fellow midfielder Craig Bryson sidelined for up to a month.
Clement told BBC Radio Derby: "We want quality rather than numbers.
"We are seeing if there is the possibility to bring in one or two."
Both Hughes and Bryson damaged knee ligaments, but Bryson should be back within a month.
Clement said the Rams will remain active in the final two weeks before the window closes
"There will be nothing before the weekend and even before Middlesbrough [on Tuesday] but we are looking," he added.
"It's a difficult process, particularly at this time of the transfer window. A lot of business has been done. We are drawing up a shortlist of good quality talent, but it is important we get the right type of player that will fit in with our culture and the way we play."
