Crystal Palace boss Tony Pulis says any January signing must be able to fit in with the locker room.
Pulis hopes to recruit in the winter transfer window, without detracting from the spirit being fostered among his troops.
He said: "It's tough, because you go into a football club and you're playing catch up. In the Premier League it's such a relentless league and you have runs of games where you're playing against teams like Chelsea where it's very, very difficult to get points.
"The spirit from the players in the past five, six games has been absolutely fantastic.
"One thing we must be careful of is that we bring players in with the same attitude of these because their attitude has been absolutely fantastic."
