London: Tottenham midfielder Dele Alli was struck on the head by a bottle at Arsenal while helping his team seal a place in the League Cup semifinals with a 2-0 victory in the north London derby on Wednesday.
The plastic bottle was hurled from the stands at the Emirates Stadium about 12 minutes after Alli scored the second goal as Tottenham won at its rival for the first time since 2010.
The England International rubbed his head but appeared unharmed as he responded by gesturing the 2-0 lead, before being led away by his captain Harry Kane.
On Twitter after the game, Alli posted an image of him gesturing the scoreline to the home fans.
Alli audaciously lifted the ball over Arsenal goalkeeper Petr Cech in the 59th minute after helping to set up Son Heung-Min's goal in the first half.
Police in helmets were also brought into the stands at the Emirates Stadium to provide a larger barrier between Tottenham and Arsenal fans.
