The Royals boss says he is "always looking for new players" and hopes to hang on to Premier League football by adding to his Championship-winning squad in the transfer window
The Royals are six points adrift of safety and have won just once this season, with their misery compounded by a 1-0 loss against fellow promoted club Southampton.
McDermott's side won 3-1 at St Mary's last season, but while the big-spending Saints were able to purchase Gaston Ramirez for £12 million over the summer, the Royals were largely limited to free transfers.
And though Reading are actively scouring the market for new additions, their 51-year-old manager is equally content to work with the players he currently has at his disposal.
"We are always looking for new players, that is part of the job really as a manager," McDermott told talkSPORT.
"Our scouting system is always trying to find players but we work with the players we have got and we don't talk about the players we haven't got.
"We will see what happens in January."
