Wolves 1 (Bosingwa-og 5)
Just a week after their heroics at Anfield, Mick McCarthy's braves were at it again as they beat reigning Premier League champions Chelsea thanks to an early own goal from Jose Bosingwa.
There were three changes to the starting line up with Sylvan Ebanks-Blake, Stephen Ward and Nenad Milijaš dropping down to the bench to be replaced by Steven Fletcher, Dave Edwards and Kevin Doyle.
Chelsea kicked-off attacking the North Bank end but it was Wolves that enjoyed a dream start as they moved into a fifth minute lead. Stephen Hunt's cross was headed out but only as far as Ronald Zubar who unleashed a terrific 30-yard drive that forced a diving save from Petr Cech.
Hunt took the corner conceded and his inswinging kick struck Bosingwa, who was stationed just in front of the line, and bounced into the net (pictured).
Richard Stearman had to clear a dangerous low cross from Salomon Kalou for the first of three successive Chelsea corners all of which provided anxious moments for the home defence. From the third Zubar broke clear and he raced well into the Chelsea half before he was eventually dispossessed.
John Terry's foul on Doyle resulted in a free-kick 30-yards out and in a central position but Hunt's lofted ball into the box was easily headed clear.
George Elokobi did well to head clear an Ashley Cole cross as Kalou ran in looking like a certain scorer as Chelsea began to pile on the pressure.
In the 28th minute Zubar won the ball off Cole and set off towards goal before slipping the ball to Doyle whose shot was easily gathered by Cech.
The visitors were a whisker away from pulling level when another cross from Cole was met by Kalou and the ball was about to cross the line until Wayne Hennessey deflected it away with his foot leaving Stearman to complete the clearance.
When a Frank Lampard corner was headed up into the air Hennessey punched out as far as Terry who volleyed high over the bar. Shortly afterwards Zubar needed treatment after a clash of heads.
Hunt was harshly penalised after winning the ball by the Chelsea corner flag. Terry pushed the midfielder on the back of the neck as he held onto the ball and both were then spoken to by the referee.
Hunt was penalised after Kalou went down but Hennessey had little difficulty in claiming Didier Drogba's free-kick.
The Chelsea pressure was relentless but as Doyle attempted to break clear in stoppage time he was pulled back by Branislav Ivanovic who was shown the yellow card.
Half-Time: Wolves 1 Chelsea 0
A few seconds after the restart Michael Essien fired high over and then Hennessey had to dive to smother an angled effort from Cole who had worked his way into the box.
Doyle won a corner off Bosingwa but Cech got in a good punch to clear Hunt's flag kick before Kalou missed a great chance for Chelsea when he shot wide of the far post after being played clean through by Lampard.
Florent Malouda headed straight into Hennessey's arms after a cross from Bosingwa, and Stearman made a perfectly timed tackle on Malouda in Chelsea's next attack.
In the 65th minute Drogba held off Stearman's challenge and hit a shot on the turn that smacked against the outside of the near post. Before play restarted Nicolas Anelka was sent on in place of Kalou.
After Malouda had tripped Matt Jarvis just outside the Chelsea box, Wolves made two changes with Ward and Ebanks-Blake replacing Doyle and Fletcher before Hunt's free-kick clipped the top of the angle as it flew over.
A minute later Malouda found himself with the goal at his mercy but his shot was two-yards wide of the far post.
Hunt beat the offside trap and raced into the Chelsea box but he was robbed by a great tackle from Essien as he was about to cross the ball.
Ebanks-Blake suddenly pulled up with what turned out to be a hamstring injury and he limped off to be replaced by Milijaš after just 13 minutes on the field.
As the game drifted into the four minutes of added time, Anelka broke clear and looked on for the equaliser but Hennessey was out of his area like a shot to make a great tackle on the French striker.
The final whistle was greeted by a tremendous cheer as Wolves moved out of the bottom three following a defensive display of the highest quality from the Molineux men against the reigning champions.
