With Arsenal already leading 3-0 thanks to an early trio of goals from Nacho Monreal, Alex Iwobi and Laurent Koscielny, Lacazette made sure to take his opportunity to show manager Arsene Wenger that he deserves to be a starter, amid reports the 'Gunners' have bid for Borussia Dortmund's Pierre-Emerick Aubameyang.
The Frenchman's moment came with 22 minutes on the clock. Mesut Ozil started the move, exchanging passes with Alex Iwobi and Jack Wilshere before flicking the ball into the path of Lacazette just inside the box.
Lacazette made no mistake, sweeping the ball past Wayne Hennessey in the visiting goal.
To make it even more special, the goal was Arsenal's 500th Premier League goal by a French player.
