Redknapp, who takes charge of his second game when fellow strugglers Aston Villa visit Loftus Road today, refused to set a points target.
But he insists the Londoners have to play like a side chasing a European spot. He said: “It’s got to be top form. We’re talking top-six or top-seven, that’s what we have to do now.
“We have given a points start to everyone and have to play catch up.
“It’s like a handicap because we are way, way off.
“It will be hard, no one is kidding themselves about that — but it’s not impossible.
“I’m optimistic. I think we can do it. I’ve not come here to age myself another 10 years.
“I think it can be done — if I didn’t, I wouldn’t have come.”
