Cesc Fabregas silenced his critics by producing a superb winner for Chelsea in a scrappy derby at QPR.
The midfielder popped up late on to deliver the visitors a crucial three points.
Chelsea boss Jose Mourinho handed Didier Drogba a rare start, with Loic Remy a late withdrawal after a training ground injury.
Rs manager Chris Ramsey went with two upfront as Charlie Austin and Bobby Zamora took on the Blues defence.
QPR gave as good as they received in a scrappy first-half. Austin went closest for the hosts, hitting a strong drive to the right of Chelsea goalkeeper Thibaut Courtois, who turned it aside.
But it was the Blues who almost took a lead into the break when Willian struck Robert Green's near post with a deep cross.
QPR opened the second-half strongly and Courtois had to be at his very best to deny Matt Phillips with a world class reaction save.
Austin went close inside the Blues penalty area before Chelsea worked a wonderful winning goal.
Green's miss-kick fell for Eden Hazard who drove at the heart of QPR's defence before the ball was eventually worked to Cesc. The Spaniard calmly passed his effort beyond a despairing Green for Chelsea's 100th goal of the season.
Chelsea skipper John Terry enjoyed the victory more than most, having endured a torrent abuse from home fans for the entire 90 minutes.
