ESPN FC's Ed Dove and Colin Udoh look ahead to Sunday's North London derby with Premier League leaders Tottenham facing an Arsenal side stuck in a mid-table rut. Udoh says this fixture is no longer "a done deal" for Arsenal as it once seemed to be and the Gunners' success comes down to Pierre-Emerick Aubameyang's ability to score. Dove points to Serge Aurier's improvement under Jose Mourinho to highlight Tottenham's turnaround.
