Torres, who has scored just once in 22 Blues games, set up both goals in a 2-0 win as the west Londoners got their Champions League group campaign off to a winning start.
“Fernando had a very good game, two assists, and it is difficult because the people all the time speak about him,” said Luiz. “It is big pressure in the head, but Fernando is a good guy and I know this season he will score many, many goals.”
The performance was a timely fillip for Torres, who has faced increasing speculation about his future at Stamford Bridge this week, despite only joining the club in January.
Winger Florent Malouda added: “It is difficult when you can see people focusing on one player in the squad. I think the whole squad work hard every day in training and I think Fernando is working very well. I would say we need to be patient, he works very hard for the team.”
