Graham Westley has threatened a summer overhaul at Preston after revealing there is a split in the camp over his methods.
Tuesday night's defeat to Brentford left North End with two wins in 14 matches following Westley's appointment as successor to Phil Brown in January.
A host of new signings since the former Stevenage boss' arrival, plus a willingness to put his faith in Deepdale youth products, has left a section of the Lilywhites severely oversized squad dissatisfied.
"When you have got a new regime coming in people do react and, let's face it, this isn't a winning camp - it was a camp that was posting poor results," Westley told Preston's official website.
"Change was needed and you would expect that the entire squad would relish a change which would demand them to get physically stronger (and) fitter.
"I have listened to the lads saying they are getting fitter and stronger and I don't understand why anybody would want to react against that, but there are players that do. When you have got that sort of split in the camp then you are working towards a summer where you can change that around, where people who don't want to be a part of it can move on."
