"But then I think it is worth pursuing. That is the approach I had last year too."
O'Neill brought in three permanent signings and a loanee last January but this time is not expecting a hectic last fortnight.
"You always felt that Shaun Maloney - out of contract at the end of the season and I obviously knew him inside out - would come," said O'Neill.
"And you felt Ashley Young was going to be here with a bit of luck for the foreseeable future and that John Carew would come in and do a job.
"We might not get the same type of luck this season but it won't be through a lack of trying."
