The Frenchman has come under fire recently for his decision to not sign a world-class striker this summer - an acquisition Arsenal fans were yearning for.
And yet despite it being widely stressed that reinforcements were a necessity for his side, Wenger has stuck by his choice, insisting that his current crop of forwards are capable of carrying the north London side's goalscoring burden.

"I think Giroud, Walcott and Sanchez can get around 20 goals without any problem," said Wenger.
"Sometimes you have to trust your players and play them. Then they get there. People want always the absolute certainty that they will be absolutely successful. It is not like that."
France international Giroud is one to be particularly struggling for form of late, given his return of just one goal in Arsenal's opening four games and woeful performances during the international break, in which he was booed off by France fans against Serbia.
Wenger, though, insists that there is no specific formula to goalscoring, and that it is therefore up to those around Giroud to also perform and chip in with goals.
"It is not a science that everybody masters and can absolutely predict how many goals everybody will get," the Frenchman continued.
"I would rather have Aaron Ramsey get 15, Mesut Ozil 15, Santi Cazorla 10. Otherwise, if you have only one player who scores, when he is injured you don’t know who will score."
There is no doubting that the aforementioned trio of fowards are capable of reaching 20 goals, but the issue remains that Arsenal are in need of a striker that can consistently spearhead their attack.
Wenger, however, places blame upon the current shortage of world-class strikers in Europe as to why he didn't complete the high-profile signing that he was urged to make.
"The strikers are South American today," said Wenger. "Europe doesn’t produce strikers any more.
"You look at countries like Germany, who played in Scotland or against Poland with Mario Gotze up front – he’s a creative midfielder.
"I don’t think it’s because they do not want to play with a typical striker but they haven’t got one who’s really convincing at the top level.
