Anelka hails Chelsea depth after Spartak Moscow win
The Frenchman, who has scored four goals in three European appearances this season, impressed in hostile surroundings as Chelsea broke clear at the top of Group F.
"What happened two years ago doesn't matter any more," said Anelka.
"It's all in the past now. We can now concentrate on playing our own game and our own football, as we did tonight. This was a tough game but, in the end, we could have scored more than we did. We have a big squad with good players throughout and, even with injuries, this shows we can go to tough places and win even when we are not at full strength. Even with some players missing, we have enough quality to play well and win."
