The Eagles boss saw his side draw 1-1 with Norwich City at Selhurst Park on Wednesday before making it clear that he was eager to make a few changes to the squad he inherited from Ian Holloway earlier this season.
"The next couple of weeks are big in respect of recruitment in terms of what we can bring in and let go," he told Sky Sports.
"If we can do some business that'll help us. We know what players we want to bring in.
"Out of respect, we'll keep them close as always."
Bradley Johnson opened the scoring for the Canaries in the 39th minute before Jason Puncheon converted from the penalty spot on the stroke of half-time prior to Leroy Fer's sending off with eight minutes remaining.
