With less than two minutes having elapsed from the opening whistle, Arsenal found themselves ahead.
Tomas Rosicky drew his bow, and let fly a deadly arrow past Hugo Lloris into the far top corner and Spurs were left shocked at White Hart Lane.
With Sandro misfiring in the Spurs attacking end, the Gunners broke on the counter.
Arsenal winger Alex Oxlade-Chamberlain worked hard to begin the counter and fed Rosicky down the right-hand side.
The Czech international worked down the entire right touchline before angling back towards the box and finding Ox back towards the middle.
Oxlade-Chamberlain was nearly dispossessed by tight defending, but he returned the ball to Rosicky before losing out, and the 33-year-old workhorse rifled home on a tight angle.
It’s Rosicky’s second goal of the season, and marks the fastest-ever goal by Arsenal against Tottenham in the history of the North London derby, according to Opta statistics.
The match has settled down since the goal, but it’s a shocking open for the visitors, and with Tim Sherwood criticizing his players for their lack of character throughout the buildup to the match, they will need to prove him wrong now more than ever.
