As Bukayo Saka shot low, hard and ultimately through Kostas Tzolakis in the Olympiakos goal to complete an occasionally uncomfortable 2-0 win, the noise from the home crowd was more a weary, sofa-flopping sigh than a roar of triumph, with the sense, finally, of a midweek putting-to-bed.

This was a game Arsenal always looked like they were winning, despite seeming to realise this a little too early in the piece against eager and purposeful opponents. Nobody attracts the stern and unforgiving eye quite like this Arsenal team, for whom squad depth, the unforgivable act of acquiring a potentially title‑winning team, is the latest crime on the rap sheet.
