Shaun Wright-Phillips insists Wednesday's shock victory over Chelsea has reinforced the belief that QPR can avoid relegation from the Premier League.
Wright-Phillips, who played at Stamford Bridge from 2005 to 2008, struck his first league goal in 969 days to secure an unlikely 1-0 win for the bottom placed Hoops.
And after securing their first win at the home of their West London rivals in 30 years, Wright-Phillips says QPR's hope has been restored.
"If Chelsea struggled to break us down, with the way we played against them, then a lot of teams will," he 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 January's remaining Premier League fixtures against Tottenham, West Ham and Manchester City that will dominate their thinking.
Striker Jamie Mackie insists their heroics at Stamford Bridge must be used as a springboard 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."
