Newcastle boss Chris Hughton will not risk wholesale changes in January.
The Magpies are currently finalising their list of targets for the winter transfer window amid speculation linking them with now free agent Sol Campbell, Sheffield United's Matt Kilgallon and Manchester United midfielder Tom Cleverley, currently on loan at Saturday's opponents Watford.
He said: "We are aware of the players who come into that. Whether we will get those targets or not, I don't know. That's something we will work towards over this next month.
"The one thing you never know is what other targets will become available because we are in a period of time when there are players who you never, ever thought would be available who you find now are.
"But I don't see us adding too much to the squad. What I have also got to be mindful of is not to disrupt too much what we have here. It's been quite a tight group that we have had here.
"What we have done so far is bring in the right type of person, and that's what we have got to make sure of again."
Asked specifically about Campbell, Hughton added: "Sol would be one of a number of players we will be assessing over the next month.
"We have got to make sure that come the end of January, we have got the right squad, we have brought in the right players - and of course, it is not only us that know about Sol's situation.
"He would be one of just a number of players we would be interested in."
