Arsenal boss Arsene Wenger admits he needs to add to his striker options.
Wenger has been impressed by striker Olivier Giroud, who has scored three times in three games, and Lukas Podolski, who netted twice at Fulham in Saturday's 3-1 win. Both are now in their second year with the Gunners.
"By scoring the goals they're proving a point and by being efficient offensively, they're proving a point," Wenger said.
"This season I think they will be more efficient, because they are quality players, they know the Premier League, they know how we want to play.
"They are doing well at the moment so let's hope it will last.
"I am sure of their quality, but what people are worried about is not only the quality, it's about the numbers to fulfil a whole season."
