Chelsea have secured their spot in the semi-final of the UEFA Champions League this season even though they suffered a defeat at home to FC Porto in the second leg of their tie which was played on Tuesday night. The Blues already had the job done in the first leg away in Portugal when they played Porto.

At Stamford Bridge, Chelsea did not play with the same aggression and character they showed in Portugal and failed to penetrate the Porto defense. The game ended goalless at half-time, with neither side registering a single shot on target.
