Chelsea manager Carlo Ancelotti has attempted to take some of the heat off £50 million signing Fernando Torres by insisting he is "not asking him to score".
When asked about the different impacts made by Torres and Luiz, Ancelotti told Chelsea magazine: "We don't have to compare them. Torres didn't score but I don't ask my strikers to score.
"I ask them to play for the team. Torres did a very good job with that. People judge him on the goals he scored but I have to look at different things about his performance. He worked for the team, put pressure on the defenders, moved well in front and worked hard.
"That's enough for me. Ask him, not me, if it will affect him but I don't think it will. I'm not asking him to score."
Torres, 26, insists he will adapt to the new style of play at Chelsea. He added: "If you want to be a top player, you have to be able to play in all these situations and I'm sure here at Chelsea I will play in different positions sometimes.
"I'm ready for this because I want to play where the manager asks me to - I know the competition is high here. My movement often depends on the game and on the other team, if they are deep or if they leave space behind. Normally the striker has to be on the shoulder of the centre-backs to leave a space for the midfielders coming forward.
"That's what I have been doing at Liverpool for the last 3½ years and it's one of the things I like to do."
