Wolverhampton Wanderers are yet to do any business during the January transfer window.
Wolves have not made any moves to date this month, but Lambert has continually stressed that he thinks his side will be busy.
And the Scottish boss reaffirmed his desire to bring in new players at his latest press conference.
He said: "There may be one or two things that happen later in the window.
"The youngsters that are coming through are pushing hard and the squad’s too big.
"One or two can go out on loan and some might leave permanently.
"We have to do that because there’s too many players.
"It’s difficult. We’re still trying for a couple to come in and to move some on."
Lambert has previously suggested that Wolves will target players with Championship experience in the January transfer window.
Wolves’ squad will also need trimming, as they brought in a whole host of new players last summer.
Former boss Walter Zenga was keen to spend the riches provided to him by Wolves’ board, but it has left the team looking bloated.
Wolves’ results have improved slightly since Lambert took charge, with the Midlands side winning four of their last eight matches in all competitions.
Lambert’s mean are next in action tomorrow, when they take on Aston Villa at Molineux.
