This was a tale of two chances, both falling to unmarked forwards just yards from goal.
The first was somehow missed when it was easier to score. The guilty party? Arsenal’s club-record signing Nicolas Pepe, all £72million of him.
Lys Mousset, a Bournemouth misfit before his summer move to Bramall Lane, cost one seventh of Pepe’s fee, yet he showed how it should be done with a first-half goal that would prove the match-winner.
The Gunners are in a good run of form and will be full of confidence they can leave the top flight new boys with all three points to keep their ambitions of a top four finish well on course.
For Chris Wilder’s side, they hope to maintain their steady start to the season as they aim to pull clear of the relegation zone by as much as four points. Follow all the action as it happens with kick-off from 8pm BST
