Promising starts are not alien to Arsenal, but in recent times, it has always been followed by a customary dip in form.
But there seems to be something different about the Gunners this season.
Since losing their opening match to Aston Villa, Arsene Wenger has guided the team to nine straight victories, including the penalty shoot-out win over West Bromwich Albion in the League Cup.
The away triumph over Swansea last Saturday summed up the improvement they have made.
With a combination of flair and steel, they took down Michael Laudrup's stylish passing side by the skin of their teeth, but it was exactly what made it all the more impressive.
A five-minute spell around the hour mark saw Arsenal suddenly spring to life, bag two goals, then close shop.
The Swans battled to the end, pulling one back with nine minutes remaining to set up a nervy ending for the visitors.
But Arsenal held on. They did it with every remaining ounce of determination and energy.
