Paul Heckingbottom is hoping for a quiet transfer window next month with a few players coming in and none of his stars going out.
Striker Adam Armstrong's loan from Newcastle United runs out in January while he has several key players who are out of contract next summer. Central defender Marc Roberts has been linked with Premier League West Bromwich Albion this week.
Heckingbottom said: "I can't see too much happening. I would love to keep everyone and add one or two. "We have to be prepared and, if players do leave, then that would just provide an opportunity for someone else whether that is a new signing or a player who is already in the building.
"We're not sure what is going to happen with Adam Armstrong yet. Newcastle probably don't know yet. He's getting an opportunity here so hopefully things carry on as they are."
Heckingbottom will also have a decision to make on the future of George Moncur. The 23-year-old signed in the summer for £500,000 from Colchester but, after not starting in the first five league games, he engineered a loan move to League One Peterborough.
Moncur, who can play up front or in midfield, netted two goals on his full Posh debut in September but has failed to score in League One since then and has only made two substitute appearances in the last seven weeks. He is due to return in January.
Heckingbottom said: "It will be a decision between myself, the club and George. We listened to George's thoughts and feelings on it in the summer. He wanted to go out on loan and that hasn't panned out as he hoped that it would.
"He is still our player and we have to make sure we give him the best opportunity to succeed whether that is here or somewhere else on loan. I want players to fight for a place but he wanted to go out and play football which is fine and that is the way I was as a player too. But he has found that you are never guaranteed a place at any football club.
"He may have had more gametime if he had stayed here than he has had at Peterborough. We had a spell when we only had one central midfielder, we wouldn't have been in that situation if we had George here."
