Manchester United needed a controversial own goal from Birmingham defender Scott Dann to salvage a point in a 1-1 draw at St. Andrews as they missed out on the chance to replace Chelsea as Barclays Premier League leaders.
Blues were incensed referee Mark Clattenburg allowed the equaliser to stand after 63 minutes, cancelling out Cameron Jerome's first half opener, and he consulted with one of his assistants before awarding the goal.
The Red Devils ended with 10 men after midfielder Darren Fletcher was sent off in the closing stages for a second bookable offence.
The draw enabled Blues to make club history in achieving their longest ever unbeaten top flight run of 12 games.
