It makes it all the more baffling on how did the backline concede 6 in one full game at Arsenal in the Carling Cup. Saying that the young guns of the Premier League outfit will soon become some of the worlds best players.
The most the Blades have conceded in one game is 2. That being against Derby County in September.
Ugo Ehiogu and Chris Morgan have been the recent central defensive pair due to the absence of Matt Kilgallon, but he returns from suspension and puts pressure on Ehiogu and Morgan not to lose their shirts.
Meanwhile Birmingham are closely behind sitting on 9 goals conceded all season. And finally, our across city rivals Sheffield Wednesday have conceded the most (24).
