Despite a victory in front of a home crowd, Jose Mourinho bluntly admitted to reporters in his post match interview that he "did not enjoy" the game.
Chelsea found themselves in the lead when Cesc Fabregas assisted Oscar to his second goal this season with an outside of the foot drive into the bottom corner.
But QPR in good fashion attempted to fight their way back into the game, exactly as they did against Liverpool a fortnight ago.
And the visitors found their well deserved equaliser with just under half an hour remaining when in form striker Charlie Austin deflected a Leroy Fer shot which was initially heading wide of Thibaut Courtois' goal.
However, the league leaders sheer quality helped them back into the lead when just over ten minutes after the equaliser, Eduardo Vargas brought down Eden Hazard inside the area.

The Belgian winger converted his penalty confidently in style to fire the Blues back into the lead. But the main talking point of the game has to be Oscar's goal of the season contender which he audaciously fired an outside of the foot angled effort on goal which nestled gorgeously into the bottom corner.
Despite Chelsea's desperate efforts to battle for a winner to keep their unbeaten run alive, manager, Jose Mourinho confirmed after the game that he was unhappy with the style of football that the squad played and consequently the Portuguese boss "did not enjoy" the game.
"I enjoyed the win. No doubt we deserved to win." But then the 51-year-old went on to discuss he was "not happy with the performance."
Chelsea will head into their midweek Champions League tie against Maribor fairly relaxed with a 6-0 aggregate scoreline, however Mourinho stated "anything is possible in football so we must treat it like any normal game."
