Fernando Torres was officially unveiled as a Chelsea player on Friday and immediately said he would not celebrate if he scores on his debut against his former club Liverpool on Sunday, dpa reported.
The 26-year-old Spaniard was bought for a reported 50 million pounds, a Premier League record, and looks set to go straight into the starting line-up for the match at Stamford Bridge.
The Spain forward has a great record of scoring in the biggest matches but said he would be sensitive to the feelings of Liverpool fans who are angry at his departure.
"First I have to play and then I have to score but I have big respect for Liverpool fans so I don't think I will (celebrate)," he said at a press conference on Friday.
Torres said he had made up his mind to leave Anfield around the middle of January, before Chelsea made their move.
"Things had changed a lot in the last year," he said. "I think they have great ambition and they are doing the right things to get back, but it will take time. I didn't have that time."
Torres said he did not feel burdened by expectation because of the transfer fee.
"The ambition of this team is to win trophies every year," he said. "That is my ambition too. I was in this situation before when I signed for Liverpool. Big money means big expectation. I'm more than ready for the challenge. I'm excited abut a new life and new era."
Chelsea manager Carlo Ancelotti was delighted to be unveiling his latest signing and said he would be a massive boost to their hopes of overhauling league leaders Manchester United.
"We are better compared to seven days ago because Fernando is playing for us and this is very good news," the Italian saod.
"Fernando is in good condition and is fit. He has no problem and trained very well in these days, he is available to play against Liverpool obviously. I don't know if he will start or maybe come on during the game. It is my decision and I will take the decision before 4pm on Sunday.
Ancelotti said it was a welcome headache to have to work out how to use Torres, Didier Drogba and Nicolas Anelka.
"Everyone knows Fernando is a fantastic striker, he has the ability and skills to score, not just to score but to play for the team, he said.
"Playing in a team with the other players the most important thing is to use his ability and quality for the team. These are our expectations, he is an unselfish player and doesn't have a problem to play for Chelsea.
"He is not a winger, he is a striker and we have to find the right shape to put him and the other players to play together.
"I never had a problem to put together players with quality. We have to try to use the training sessions to improve our combination up front but I don't think this is a problem."
