Tottenham Hotspur beat Arsenal in the first north London derby outside of the UK thanks to Pape Matar Sarr's excellent long-range chip.
The match, which was played in front of a stadium-record crowd of 49,975, gave a glimpse into what both sets of supporters can expect from their sides this season.
Sarr lobbed the ball over David Raya from near the halfway line in the 45th minute after Spurs won the ball back in midfield.
