Didier Drogba scored two goals and set up another to help Chelsea qualify for the knockout phase of the Champions League on Tuesday as Group E winners.
The under pressure London side delivered a clinical 3-0 victory over Valencia at Stamford Bridge.

Needing a victory or a scoring draw to progress at Chelsea's expense, two-time finalists Valencia were allowed to dominate possession but were stifled by the hosts' packed defence.
The victory meant Chelsea advanced to the last 16 for the ninth straight year, and that Bayer Leverkusen were relegated to Group E runner-up after being held to a 1-1 draw by already eliminated Racing Genk.
