This match – and who knows, perhaps the next chapter of these sides’ seasons? – changed in five minutes bookended by two pieces of brilliance by Mohamed Elyounoussi.
With nearly an hour gone at St Mary’s, Arsenal led 1-0 through Granit Xhaka's early goal when Gabriel Jesus nicked the ball off Ibrahima Diallo in midfield and raced in behind. Martin Odegaard fed his striker, who drove at goal, only to be denied by a desperate, last-ditch lunge by Elyounoussi.
The winger had spent most of this afternoon as an auxiliary full back as Southampton struggled to contain the league leaders.
