Rangers' 19-match unbeaten streak came to an end when Watford ran out comprehensive 3-1 winners in front of the television cameras last Friday.
Warnock takes his side to Leeds this Saturday knowing a defeat could see their lead at the top cut to one point.
He said: "The confidence is bound to have taken a knock. But when you look at other results, everybody's the same really.
"Just look at Chelsea. They only have one win in seven. You just have to work your way through it and get back to basics."
