Chelsea took command of their Champions League quarter-final against Benfica after Salomon Kalou's lone goal earned them a first-leg victory at the Estadio da Luz.

The Blues had been described in the build-up as "not as good as we used to be" by a subsequently rested Frank Lampard, but they were comfortable enough during an low-key first half as Benfica moves came to nothing.

Oscar Cardozo volleyed wide after taking a long ball on his chest (19) but it was the visitors who had forced the only meaningful save by the break, Raul Meireles' sweetly-struck skidder parried by Artur (40).

Cardozo would have rewarded a brighter Benfica after the restart had David Luiz not stood firm on the line but there were fine margins at the other end when Juan Mata rounded the goalkeeper, only to hit a post (61).

Fernando Torres had been erratic in front of goal but eager in appoach play, and it was a fine break down the right he made before affording Kalou a simple finish and the timeliest of first wins this term in Europe for Chelsea.
