"You've got to give tremendous credit to QPR. With 13 minutes to go they are down, as they have a horrific run in. Liverpool were cruising at 2-0 up but they fell apart and it's now four defeats in five. The last thing you want at Liverpool is to be called a cup team. You cannot keep saying they are playing great but getting beaten. They have to eradicate these problems."
The win came on the back of a
2-1 loss against Bolton
when QPR felt aggrieved at a goal being disallowed when Clint Hill's header appeared to have crossed the line.
But Hughes added: "Today [against Liverpool] maybe there was a shift in the amount of luck we possessed. We just weren't to be denied."
A spectacular Sebastian Coates volley and a Dirk Kuyt effort had put Liverpool in a comfortable position before QPR's comeback.
Shaun Derry and ex-Liverpool forward Djibril Cisse pulled QPR level before Jamie Mackie struck an injury-time winner.
"We've come back from a situation where we looked dead and buried," said Hughes, whose side have still have to play the top five in the Premier League.
"I didn't think we deserved to be 2-0 down. We had nothing to lose and thought 'lets go for it', which is what we did.
"We took the game back to Liverpool. Recently we have felt aggrieved as things have gone against. But that will give us huge belief now.
"There was some great performances and everybody deserves a mention. I thought the crowd were fantastic as they never lost faith in us. Once we got a little bit of momentum they drove us over the line."
No explanation for defeat - Dalglish
Liverpool have lost four of their last five league game in the midst of winning the Carling Cup and progressing to the FA Cup semi-finals.
Reds boss Kenny Dalglish was left as stunned as his players at his team's capitulation, which leaves them 12 points behind a top four place.
"It's very difficult to explain," said the Scot. "We played some fantastic football. We were deserving of our lead and we weren't even under pressure.
"With a bit of care and better finishing we might have been three or four up at half-time.
"You just couldn't see a goal coming from them and maybe the luck they didn't get against Bolton they got here."
