Sunderland 2-1 Chelsea: Blues not scoring enough - Jose Mourinho

Chelsea boss Jose Mourinho says his team do not score enough goals after they suffered a 2-1 extra-time defeat away at Sunderland in their League Cup quarter-final.

The Blues seemed to be heading to the last four until a late Fabio Borini equaliser took the match to extra time, and Ki Sung-Yueng thumped in the winner to send the Black Cats into the semi-finals.

Mourinho says that in future his side may have to "play less football" and focus on not conceding but says that is something he does not want to do.
