But the football and scoreline were not the main talking points after the game.
Bukayo Saka’s low shot deceived Bart Verbruggen for the only goal as it took a flick off Carlos Baleba, who had earlier had a great chance to score.
Albion gave a hard-working, passionate and energetic display but without the quality in key areas to pierce the table-topping defence.
But most of the chat afterwards was about the Gunners methods of halting play, wasting time and breaking any sort of rhythm in the contest.
Our match audio looks at the football and the good and bad of the Albion display.
But we also talk about the spectacle as well, what was being said before the game and what the reaction was like afterwards.
And why the whole thing feels the wrong way around.
Either way, all the talk seemed to be about Arsenal although Fabian Hurzeler said he was keen to talk about his own side.
His said he was proud of their efforts.
But ultimately it was not quite enough - and not enough to alter the frustrated tone after the game.
