Newcastle United are set to be active in the January transfer window.
Although the 54-year-old boss was not prepared to discuss names of transfer targets, he says that he is constantly talking about who to bring in behind the scenes.
Newcastle realise that they need to bring in quality at the next available opportunity, to strengthen their chances of survival.
And McClaren said: “Privately behind the scenes, we are planning, but until things happen, we will say nothing.
"To be fair, that is my policy. I don't like speculation that we are going to do this or going to do that. The window is not open, we still have two games before it opens.
"Believe you me, we are talking all the time behind [closed doors]. We don't plan to do anything in public."
Newcastle have been linked to a number of players ahead of the January transfer window.
Newcastle are also said to be chasing deals for Tottenham Hotspur winger Andros Townsend and Swansea City midfielder Jonjo Shelvey by the Daily Mail.
Newcastle are currently just one place above the drop zone, having accumulated 17 points from their first 17 matches, but their more recent form suggests they could have turned a corner in their bid for top flight survival.
