The Magpies manager is "analysing" whether or not the relative paucity of transfer activity before the season was a mistake, with his side having lost four games in a row
The Magpies have endured a difficult start to the campaign, beset by injuries and suspensions, and sit just two points clear of the relegation zone following a run of four consecutive defeats.
And, with Vurnon Anita the only regular first-teamer recruited in the summer, Pardew told Sky Sports: "We have been unlucky but we are in the process of analysing whether we under-cooked it [the transfer window] and that's what we should do. It would be silly not to."
A number of key players such as Yohan Cabaye and Steven Taylor are set for long spells on the sidelines and the Toon boss is considering dipping his toes further into the transfer market in January.

Newcastle welcome Wigan to St James' Park on Monday in a vital Premier League clash and Pardew feels that the Magpies must stay focused if they are to bring their losing run to an end.
"We have to win a game," he declared. "We are desperate to win and sometimes desperation to win leads you down wrong avenues, so we have got to be careful.
"When you have lost two or three - and now four for us - you start doing other people's jobs, and it's very important just to focus on your job and do your job."
