Alexandre Lacazette may still be adjusting to a new country – but he is enjoying his home comforts in North London.
The Frenchman pounced to head home the opener on 20 minutes before adding another from the spot after the restart.
And that ensured that he has found the net on his first three home league matches for the club.
According to the Sun, he is the first man to do that for the Gunners since Brian Marwood in September 1988.
The decision to award Arsenal a penalty in the second half was met by cheers from the Emirates faithful.
But it was extra special as it was the 100th awarded to them in the Premier League.
And Lacazette stepped-up to mark the occasion by sealing the points.
