The regularity with which Chelsea have despatched all-comers this season is breeding a sense of familiarity bordering on the tedious. Robert Huth's goal, after just six minutes, for instance, immediately diminished any uncertainty about the outcome of this tie. But, to be fair to Mourinho, he gave injury-hit Birmingham credit for trying to make a contest of it. "We were a bit poor in the second half because of Birmingham's improved performance," he said.
