Just 11 matches stand between them and relegation, with seven points currently separating them and safety.
"It is another game down, but no-one has stretched the margin," QPR forward Mackie said. "It's important for us to try and get a result, a few back-to-back results, so we could be in there.
"It is going to be hard but we've got to keep going, keep trying to play and get a result. That's all you can do.
"I think we were playing the champions, in my opinion. They are a top draw side and he (Rafael) has scored a worldie. If he hadn't done that, maybe we were in the game.
"It's hard when we keep going 1-0 down and have to chase a game. It's tough.
"Next is Southampton and if we can get results against the teams in and around us it is almost like a double game."
