West Bromwich Albion defender Gareth McAuley has taken aim at Crystal Palace's winter market campaign.
Palace landed Tom Ince on loan and sealed permanent deals for Wayne Hennessey, Scott Dann, Joe Ledley and Jason Puncheon.
McAuley said: "If you end up bringing too many new faces in, it can end up going the other way and upsetting the players that have got Palace promoted and been working away for them.
"We will see how they go. We just have to concentrate on ourselves and make sure we come away with a result."
