Chelsea boss Guus Hiddink says a motivated Didier Drogba would have any defence running scared.
"I would agree he has the killer's mentality," said Hiddink. "He seems to terrify defenders. If you have to play against him it hurts.
"He is very strong and brave because he doesn't know what is happening behind his back.
"We don't demand one goal every game but when he is playing the way he is, others also score.
"I saw him at the World Cup in 2006.
"He was very strong, even though the Ivory Coast did not go through. You could see what the potential was, you just have to deliver and he is delivering perfectly.
"He is also talking in the dressing room and giving an example to others."
