Tougher tests are looming but Arsenal’s fluent progress continued with this demolition of Norwich.
Bukayo Saka led the way with two goals, either side of one by Kieran Tierney, followed by a penalty converted by stand-in captain Alex Lacazette and a late goal by Emile Smith Rowe.
It is five wins and a blaze of 19 of goals in five games since Mikel Arteta axed captain Pieree-Emerick Aubameyang.
Perhaps not against the strongest opposition. Norwich were easily brushed aside here with the look of a team doomed to the drop.
Alexandre Lacazette slotted a penalty for Arsenal to make it four and continue the visitors' dominance
Saka doubled his tally for the afternoon on what was one of the youngster's best displays of the season
Tierney slotted into the corner to dampen the mood at Carrow Road for Dean Smith's struggling side
Arsenal have a healthy balance.
