The west London club remain bottom of the Premier League table following their goalless draw at Loftus Road where Christopher Samba and Andros Townsend made their Rangers' debuts.
And Redknapp said: "Chris Samba was fantastic today. He's not played since November.
"We asked him how he was and he said he was about 40 per cent fit. If that's 40 per cent, I don't know what he'll be like when he's 100 per cent. He was outstanding.
"And Andros had an outstanding game too. People keep talking about big money - I think he's on about three thousand a week.
"I think we'll get good value out of him. Absolutely brilliant today. He never stopped working. He's a young player with a big future."
As for his team's overall performance, he added: "I couldn't have asked for more. We just needed a break.
"They gave everything. We just need to turn draws into wins and you don't get a better opportunity than we had today.
"We're unbeaten since the turn of the year so we've just got to keep going."
As for Adel Taarabt's penalty miss, he went on: "That's how it goes. Adel was outstanding again. It's just one of those things. If we score, then we win the game, there's no doubt."
