That result was very significant. A new high water mark for progress under Arteta. Aside from the U10's defending in the first 10 minutes the way a team with few first choices (Leno, Tierney, Xhaka, ESR) available I was super impressed by the way they rallied and played some good football away from home against a team of quality. LC never looked in the game even after their goal.
Special shout out to VAR too, got both calls spot on in a weekend where it was a bit of cluster...
