While I'm watching this game, I just keep thinking about all the players who Arsenal aren't able to call on: Big Gabi, Concerned Gabi, Kai Havertz, Tomiyasu, Calafiori. It's not just who's available today. It's who might have been available during the week so that other players could have a rest.
Everything in this game has been such fine margins. Maybe a slightly better or slightly more rested player would have been enough to make the difference.
OTOH, even without reinforcements, next season should go so much better as long as there isn't another injury crisis. And "so much better" than finishing second (hopefully) and making the CL semifinals... That's promising.
