Within three minutes, Chelsea were level through Diego Costa and you have to wonder how the game would have panned out, had the Belgian converted - though it's also worth noting the Blues had a strong penalty shout for a foul on Ilkay Gundogan, too.
Birmingham had a strongshout for a penalty while Emile Heskey also had a couple of decent chances, but the draw was a fair result as neither had the necessary guile or cutting edge to open the scoring as two solid defences prevailed.
