Olivier Giroud has pleaded for patience from the Arsenal fans as he looks to fill the void left by Robin van Persie's exit.
Arsenal began life without van Persie with a goalless draw at home to Sunderland on Saturday.
Gunners boss Arsene Wenger accepted his side lacked a cutting edge in attack following the stalemate with Sunderland at Emirates Stadium.
Giroud, who came off the bench against the Black Cats, missed the best chance of the game when he fired wide when put through on goal late on.
However, after his 21 goals helped Montpellier to the Ligue 1 title last season, the 25-year-old is confident things will all soon fall into place with Arsenal.
"It was a game ball, but the coach told me that I had not to worry about it," said Giroud. "This could have been the dream start, but in Montpellier, I did not score for my first game, so I am not worried. Here, I will have plenty of chances and I will score."
Giroud added: "Last season was wonderful here for Robin, but before that, he took time to settle.
"I am just asking people to be a little patient with me.
"I am not here to make people forget Robin, because he has made beautiful things here, but I just want to bring something new.
"However, I am under no more pressure than that, because if I think about that when I go onto the field, I will play with the handbrake on.
"I know Arsenal is a great club and needs a striker ready and efficient quickly.
"I need games to get confidence, and it is up to me to succeed."
Wenger accepted Arsenal lacked balance in attack against Sunderland.
Giroud believes that is something which can easily be rectified.
"It is true that we do not always cross on the first chance, but it is something we have to work on," he said.
"This is important for us because teams come here to defend and we often got the possession. We need be more effective in the final pass."
