Arsenal's new-found defensive resilience will be put to the test Sunday against a Manchester City team that's set to feature fit-again striker Sergio Aguero.
The only goals Arsenal has conceded in five matches this season have been from a penalty in the 2-1 win over Montpellier in the Champions League, and from a goalkeeping error by Wojciech Szczesny in last weekend's 6-1 rout of Southampton.
Much of the credit for Arsenal's obduracy at the back has gone to recently hired assistant coach Steve Bould, who was a member of the famously stingy Arsenal defence of the 1990s.
Bould says "we will go to Manchester City with a bit of confidence."
Both sides are unbeaten after four Premier League games and have eight points, two behind early leader Chelsea.
