Shaun Wright-Phillips insists Wednesday night's startling victory over Chelsea has reinforced the belief that QPR can avoid relegation from the Barclays Premier League.
Wright-Phillips struck a wonderfully-taken opening league goal since arriving at Loftus Road in August 2011 as Rangers left Stamford Bridge with their first win there in 30 years.
It was the perfect response to Sunday's meek 3-0 surrender to Liverpool, a result that prompted manager Harry Redknapp to hold a meeting with his players to convince them that the club will survive in the top flight.
Rangers' position remains precarious - they prop up the table, five points adrift of safety - but the performance against Chelsea has restored hope to Loftus Road.
"If Chelsea struggled to break us down, with the way we played against them, then a lot of teams will," Wright-Phillips said.
"We've never stopped believing we could escape ever since we got in this situation.
"We still believe it strongly and it was a great relief to get that result at Stamford Bridge.
"Away from home we haven't been the best and we've dropped a lot of points, so this is something we have to consolidate now.
"We tried to frustrate Chelsea and catch them on the break and we did that well."
QPR host West Brom in the third round of the FA Cup on Saturday but it is the month's remaining league fixtures against Tottenham, West Ham and Manchester City that will dominate their thinking.
Striker Jamie Mackie insists their heroics at Stamford Bridge, which were founded on defensive organisation and commitment, must be used as a launchpad to safeguard their place in the top flight.
"It's important that we continue displaying the belief we showed last night, otherwise a massive result like that can be wasted," Mackie told talkSPORT.
"When we stayed up last season we got an unbelievable result against Liverpool when no one expected it. It gave us belief, we got some results and it kept us up.
"We weren't good enough when we lost 3-0 to Liverpool and it hurt as a professional.
"At Chelsea, we worked for each other, there was no selfishness out there and that is the only way to get out of trouble."
The intervention of West Ham has prevented Redknapp from signing Joe Cole - his main transfer target - but the Rangers manager revealed he is to give former Chelsea and Portsmouth centre-back Tal Ben Haim a contract until the summer.
Redknapp stated there are no further signings imminent and must check on the fitness of Junior Hoilett, who limped off with a hamstring strain early in the capital derby.
