He was pleased with the attitude his side showed this afternoon.
"It's the players that go and do it," Lambert said.
"They are the most important people at the club along with the people that come and watch it.
"I have trust when we go on the field of play that they are going to perform and I've done that for the past two years. I have trusted them and they have just been a brilliant, brilliant group to work with.
"For 10 to 15 minutes QPR put us on the back foot, but they are a really good side.
"You can see why with the players that they have got and they were really, really good. But, after that, I thought we regrouped and deserved to win the game."
