Ipswich Town boss Paul Jewell has said he will cut down the size of his squad in January, while trying to bring in "quality" signings.
Jewell, who has been told he will have funds to spend in the new year, has brought in 12 players since the end of last season.
"I think we need to trim the squad a little bit," he told BBC Radio Suffolk.
"We've got lots of numbers but we'd like a bit more quality. Sometimes you have to trim it to move forward."
The Town boss will be in the market for a central defender when the transfer window opens, admitting he is "light in that area at the moment".
Damien Delaney and Ibrahima Sonko are both out injured, while Danny Collins will return to parent club Stoke after the Derby match on 17 December.
Sonko's hamstring problem has been an ongoing concern since he signed a one-year deal in August.
"He's been carrying it really and we've just been getting him by," Jewell said of the 30-year-old centre-half.
"But for his sake and the team's sake we need to be able to rely on his fitness and for him to be 100% certain in his hamstring.
"In fairness to him he's got through games but it's caught up with us a little bit."
And Jewell will also wait until January before trying to tie down midfielders Josh Carson and Grant Leadbitter, who are both out of contract in the summer, on longer deals.
"Josh had been away. I spoke with Grant's agent and [owner] Marcus Evans about it and I think they seem pretty comfortable letting it go for the time being and we'll see where it goes in January," he said.
Meanwhile, midfielder Lee Bowyer and striker Nathan Ellington have returned from injury and are in contention to face Nottingham Forest on Saturday.
Forward Daryl Murphy remains a doubt.
