Mikel Arteta’s young Gunners were outstanding during the Premier League clash, thanks to goals from Gabriel Martinelli and Smith Rowe.
Early in the second half, Martinelli broke the deadlock for the home side and despite Fabianski saving Lacazette’s penalty, Smith Rowe came in to seal the victory for the visitors.
West Ham put forth a valiant effort but were underwhelmed, and Coufal’s questionable dismissal will not sit well with the Hammers.
Arsenal deservedly won this game, having taken 21 shots to West Ham’s seven.
In the second half, they stepped it up a notch. Their reward is a one-point advantage over West Ham in fifth place in the Premier League table.
At the moment, the top three appear invincible, but the race for fourth looks interesting.
Arsenal, on the other hand, has plenty of reason to be confident ahead of a busy festive fortnight, while West Ham has a more straightforward schedule ahead of them.
They’ll certainly put up a fight for the final Champions League slot.
“To see that chemistry between team and crowd is unique – and I’m so proud of it.” – Mikel Arteta
