Chelsea remain top of their Champions League group after first-half goals from John Terry and Nicolas Anelka helped them to seal a comfortable 2-0 victory over Marseille at Stamford Bridge.
Carlo Ancelotti's side are now ahead of Spartak Moscow on goal difference after the Russians defeated MSK Zilina 3-0.
Marseille, managed by former Chelsea player Didier Deschamps, now face a real struggle to qualify for the knockout stage of the competition.
Chelsea went into their Group F game on the back of two successive defeats to Newcastle in the Carling Cup and Manchester City in the Barclays Premier League.
Deschamps had called for his side to show the same physical prowess and counter-attacking guile that City used to overcome the Blues at Eastlands on Saturday, but his plan went awry when Chelsea took the lead in the seventh minute with their first real attack of the game.
Florent Malouda's shot was deflected for a corner and when Gael Kakuta aimed it at the near post, captain Terry stole in to flick the ball home.
Chelsea's night got even better in the 27th minute when Stephane Mbia was harshly adjudged to have handled Michael Essien's attempted cross.
The Marseille defender was booked for the misdemeanour and Anelka rubbed salt into their wounds by tucking away the resultant spot-kick with ease.
Marseille had barely troubled Chelsea goalkeeper Petr Cech in the opening period but the French champions picked up the pace after the restart. Andre-Pierre Gignac, who had been largely kept well marshalled by Terry and Alex, sent an overhead kick straight at Cech.
Chelsea went close to adding a third in the 67th minute but a fantastic 35-yard free-kick from Alex hit the inside of the post with Marseille goalkeeper Steve Mandanda well beaten.
