Gunners stun Spurs 2-0 to give Wenger bragging rights

Mustafi's header looped over the Spurs defense from a disputed free kick and goalkeeper Hugo Lloris was unable to get anywhere near the ball as it pinged off the crossbar into the goal in the 36th minute.

Sanchez's goal came five minutes later after Alexandre Lacazette's run down the right. The forward put in a crisp cross, which Sanchez had trouble controlling at first as it bounced down off his knee. But the Chilean composed himself at the near post to fire the ball over Lloris, who hesitated coming off his line to deal with the danger.

Just when Spurs fans thought the balance of power had irreversibly shifted in north London, Arsenal turned back the clock to offer a glimpse of its past dominance. There was slick passing, the three Arsenal forwards galloped past Spurs defenders with ease at times, and the usually shaky Gunners back line managed to hold its nerve this time.

"I think we played with purpose, good concentration, a desire to be always efficient," Arsenal manager Arsene Wenger said. "Our concentration was very high ... Overall, it was a very intense game."

Tottenham started the day in third place and the result left Spurs with 23 points, one more than Arsenal.

The visitors had come into this match on a high, not only above Arsenal in the league but finishing in front of the Gunners last season for the first time in more than two decades.

Spurs are in the Champions League this season, while Arsenal is in the Europa League, and they impressed the football world with a shock win over Real Madrid in the group stage.

But Arsenal was the bigger side Saturday, managing to shut down star players Harry Kane, Dele Alli and Christian Eriksen to claim bragging rights in north London.

Eriksen looked nothing like the player who scored a hattrick for Denmark against Ireland during the international break.
