Arsenal could have gone top of the Premier League with victory here – moving ahead of Chelsea and Manchester City – and all the omens seemed good for them.
The Gunners were in prime form – they remain unbeaten since the season’s opening day – and faced a Spurs side in reduced circumstances, without a win in six games and missing the influence of injured defender Toby Alderweireld and midfielder Dele Alli.
With Kane also returning after a seven-week absence, Arsenal would have entered this north London derby high on optimism – and yet had to settle for a draw.
Arsenal were pushed on to the back foot for the first 20 minutes but then exerted their authority to lead by half-time, only to be knocked off track by the concession of that cheap penalty.
The Gunners still showed plenty of grit but in the end they did not possess enough guile to unlock a resolute Spurs defence, who held out in relative comfort for a point.
