No matter how far Arsenal go in this competition, no matter where their fine start to the season eventually leads, one thing is certain: this victory will, before long, be relegated to a footnote in their upward journey under Mikel Arteta.
Zurich were already eliminated. They sit bottom of the Swiss Super League and this, ultimately, was a win that served only to cement Arsenal’s place atop Europa League Group A.
But the last seven days have been a curious live experiment of their mettle and mental toughness. Defeat by PSV, when Arsenal were fortunate to lose only 2-0, could have wobbled lesser sides.
