Warnock remains bitter over the way Mark Hughes succeeded him at the Rs last season.
"If Harry had been in charge at the start of the season I don't think there would be any problems," Warnock told 'Open All Rs'.
"The problem is that there has been a divided camp in there. I would imagine quite a lot of bitterness or envy, with people who have come in on lucrative contracts and other lads doing a lot of work on relatively low wages.
"That doesn't create the togetherness you need. That was evident on Sunday (against Wigan).
"I am right behind Harry. I feel like it is my club again. That is how it should be."
