United 1-1 Chelsea, November 2006(02 of11)
Open Image ModalWith United 1-0 up in this top of the table clash, Wayne Rooney was tugged back by Didier Drogba inside the penalty area, only he opted to stay on his feet. Chelsea later levelled and claimed a draw at Old Trafford, although United were rightly aggrieved not to have received a penalty (credit:Getty Images)
Arsenal 2-2 United, November 2007(03 of11)
Open Image ModalAdmittedly, Webb's error here was amplified by Sir Alex Ferguson, but it warranted more coverage than it received at the time. Substitute Louis Saha, who unlocked the opening which allowed Ronaldo to put United ahead in the top two's encounter, was inexplicably adjudged to have made a foul while killing time. United's concentration wavered and Arsenal nabbed a last-gasp equaliser
Manchester City 0-1 United(04 of11)
Open Image ModalCristiano Ronaldo was sent off for the second time at Eastlands for two bookable offences. The first was for a foul on Shaun Wright-Phillips, when he had actually played the ball. The second was for stopping the ball with his hands when attacking a corner. Ronaldo protested he heard a beep, which would explain why he stopped play when he should have doubled United's lead. Webb, however, flourished the yellow, then red, card (credit:PA)
United 2-1 Blackburn, February 2009(05 of11)
Open Image ModalA classic case of atoning for an error. United should not have been awarded a corner, so when Jonny Evans stooped to head them ahead again, Webb penalised him for a phantom foul (credit:Getty Images)
United 5-2 Tottenham, April 2009(06 of11)
Open Image ModalYes, Webb should not have given a penalty for Heurelho Gomes' challenge on Michael Carrick, which was such an appalling decision he later apologised.However, with the scoreline goalless, Wilson Palacios launched a two-footed challenge on Cristiano Ronaldo (much alike Mathieu Debuchy's on Claude Yacob) but was not even booked, when he ought to have received a red card (credit:PA)
United 2-1 Liverpool, March 2010(07 of11)
Open Image ModalTwo wrongs don't make a right. Webb incorrectly gave United a penalty but also incorrectly booked Javier Mascherano for his tug on Antonio Valencia, when he had denied a clear goalscoring opportunity (credit:PA)
United 2-1 Chelsea, May 2011(08 of11)
Open Image ModalBranislav Ivanović emerged as a teflon figure during these clubs' four clashes in the space of two months. The Serb targeted Wayne Rooney time and again and although he was booked (a minor miracle), he somehow escaped a red card (credit:Getty Images)
Chelsea 3-3 United, February 2012(09 of11)
Open Image ModalGary Cahill, making his Chelsea debut, was lucky to last the 90 minutes when he upended Danny Welbeck and was the last man, with the score 0-0. Welbeck later got his revenge when he conned Webb into awarding him a penalty in the second-half (credit:PA)
United 2-1 Liverpool, January 2013(10 of11)
Open Image ModalControversy was largely absent from this encounter, but United's task might have been made easier had Webb shown Glen Johnson a second yellow card for a late foul on Antonio Valencia (credit:Getty Images)
