Chelsea warmed up for their Champions League clash against Barcelona with a 1-0 victory over West Ham thanks to Salomon Kalou's winner and Petr Cech's penalty save.
Kalou struck in the 55th minute at Upton Park but it needed Cech to save Mark Noble's penalty to keep them ahead.
The celebrations for Kalou's goal were marred by objects being thrown in the direction of Frank Lampard and John Terry.
Lampard created the first chance in the 16th minute when he slid the ball through to Florent Malouda - but the Frenchman dragged his shot wide after racing through.
Kieron Dyer, making his first start since August 2007, should have given the hosts a lead shortly after but he shot tamely at Cech after Diego Tristan had split the Chelsea defence.
Lampard saw a volley flash wide, a second went straight at West Ham goalkeeper Robert Green and Noble bravely blocked another.
John Mikel Obi was needed to clear off the Chelsea line when Tristan prodded towards goal after Noble's corner was nodded down by Matthew Upson and Cech was out of position.
The visitors were ahead 10 minutes after the restart. Lampard floated a cross to the far post where Kalou took one touch before planting his finish into the empty net for his ninth of the season.
Nicolas Anelka should have doubled the lead when Juliano Belletti sent him through but Green rushed out to block, while the Hammers were given their penalty 20 minutes from full-time when Herita Illunga's shirt was pulled by Kalou.
Noble's penalty was struck well but Cech leapt to his left and tipped away the effort.
