QPR stun Chelsea as Liverpool beat Sunderland
Chelsea's recovery under Rafa Benitez was brought to a shuddering halt by Queens Park Rangers on Wednesday as the Premier League's bottom team won 1-0 in the west London derby.
QPR's first win in the topflight at Stamford Bridge since March 1979 was secured by Shaun Wright-Phillips scoring against his former club.
The end of Chelsea's four-game winning run in one of the biggest shocks so far this season left Benitez's side fourth in the standings, 14 points behind leader Manchester United.
"Maybe in odd areas we were tired,'' Benitez said. "You could see we didn't have the intensity and the pace on the pass and the movement that we were expecting.''
Everton is only two points behind after beating Newcastle 2-1, but has played a game more than both Chelsea and sixth-place Arsenal.
Liverpool still has its sights on the top four, beating Sunderland 3-0 to move seven points behind Chelsea but having played a match more.
Benitez's decision to make five changes from the Chelsea side that beat Everton at the weekend appeared to backfire, with Chelsea struggling to impose itself with midfielders Eden Hazard and Juan Mata, and defender Ashley Cole among those watching from the bench.
"We cannot carry on with the same players every game,'' Benitez said. "If you are playing a team that is bottom of the table at home you have to trust your players.''
One of the players handed an unexpected first league start, Marko Marin, was fortunate to last beyond the fourth minute after only receiving a yellow card for a studs-up challenge over the ball and into Stephane Mbia's shin.
QPR's breakthrough came when David Luiz only half-cleared a corner in the 78th minute, and Adel Taarabt teed up Wright-Phillips to smash the ball into the net of the team he left in 2008.
