The hosts battled on until the fourth quarter, when the Gunners went on a rampage.
Saka should get the spotlight for his two goals, but Arsenal put on a fantastic team effort.
They’re in terrifyingly excellent shape. Arsenal’s victory cements their place among the top four teams in the Premier League.
They lead Tottenham by six points, despite the fact that Tottenham has three games in hand.
At the moment, the fourth appears to be theirs to lose. Norwich remains at the bottom of the table. They’re still only three points off of a playoff spot, but their goal differential has plummeted yet again.
The Gunners will now expect to play Wolves in two days, while Norwich will visit Crystal Palace.
With matches coming hard and fast at this time of year, neither team will linger too long on the outcome.
