The Germany international played the full 90 minutes and set up Kieran Gibbs’ goal midway though the second half.
The Gunners missed the opportunity to overtake Manchester City who drew with Aston Villa earlier today.
Arsenal won the first north London derby of the season after beating Spurs 2-1 at White Hart Lane in the third-round League Cup clash back in September. The last time Tottenham beat Arsenal away was back in 1993.
