Arsenal manager Arsene Wenger insisted his side will soon rediscover their goal touch ahead of Sunday's Premier League game away to Liverpool.
Arsenal sold top-scorer Robin van Persie over the summer while bringing in creative options in Olivier Giroud, Santi Cazorla and Lukas Podolski.
Both Arsenal games this season have finished in goalless draws.
Wenger admitted his side is suffering "a lack of understanding" but believes the goals will come.
"The more you speak about the problem the bigger it becomes in our game," Wenger said. "I think Giroud has not to think he has to replace Van Persie with the number of goals he has to score. We want to play well as a team and if you play well as a team you score goals.
"I do not listen to much of what people say. I listen and I try to see if it is exaggerated or not. I have worked for 30 years on a football pitch every day and I know what it is to improve a football player and what it is to go out morning and afternoon. Not everyone can say that."
Liverpool are also in the process of rebuilding and without a win so far this season, although only two ghastly defensive errors denied them a win against Manchester City last week. Liverpool will be without Lucas who suffered a thigh injury last week that will keep him out for three months.
With leaders Chelsea not in action because of the European Super Cup, Swansea City and Everton, the other two sides with 100 per cent records, could pull level at the top.
Swansea, who have scored eight and conceded none in their two games so far, host a Sunderland side likely to include both new signings, Adam Johnson and Steven Fletcher, while Everton go to West Bromwich Albion.
Tottenham Hotspur manager Andre Villas-Boas looks for his first win since taking over at home to Norwich City, who have lost both games so far. Spurs could hand midfielder Moussa Dembele a debut after completing his signing from Fulham.
Champions Manchester City, disappointing in drawing against Liverpool last week, are home to QPR, who are managed by the former City boss Mark Hughes.
After successive defeats pressure is mounting on Hughes, who has spent heavily in the transfer market and could give a debut to the Brazil goalkeeper Julio Cesar.
Manchester United go to Southampton on Sunday and Aston Villa, after two defeats, travel to Newcastle United.
West ham United host Fulham in the early game on Saturday and Wigan Athletic entertain Stoke City.
