Tottenham shrugged off a two goal deficit at half-time to score three times in the second half to triumph 3-2 at the Emirates Stadium against North London rivals Arsenal. Arsenal looked comfortable at the break, leading 2-0 against a ragged Spurs side and looking on course to make it 18 unbeaten home games against their near neighbours.
The Gunners took an early lead when Samir Nasri finished from a tight angle and Marouane Chamakh made it 2-0 from close range.
Chamakh should have made it three but delayed too long and how crucial that miss was to prove to be.
Early in the second half Gareth Bale reduced the deficit as the visitor's suddenly looked threatening.
In the 67th minutes Cesc Fabregas handled and Rafael Van der Vaart made no mistake from the penalty spot.
The Gunners hit back and had chances to regain the lead but it was Spurs who recorded a famous victory five minutes from time.
Younes Kaboul flicking home a free-kick to give the visitor's their first league win at Arsenal since 1993.
For Arsenal it was missed chance to head the Premier League, if only for a few hours.
