With the man now at the Gunners helm facing more uncomfortable questions regarding his future, a host of names have been offered up as possible candidates to fill a coaching void.
But they could not conjure it up and Arsenal had lost four games in a row for the first time since October 2002.
For Brighton it was three priceless points and a first victory over a top six team. Petr Cech punched the incoming cross away from the far post, but he didn't get much power on it, and it went straight to Lewis Dunk, who volleyed it back toward the middle of the goal for the first score of the game.
Arsenal have the opportunity to change the tide with a much-needed away win to Brighton, now 12th in the Premier League, after criticism from pundits such as Gary Neville aimed at the likes of Aaron Ramsey and Granit Xhaka.
Murray's header, his sixth goal in 2018, put Brighton two up after a mistake by Laurent Koscielny, prompting an angry response from the travelling supporters.

She also downplayed claims the White House was in a state of "chaos" because of the number of senior staffers coming and going. McMaster "isn't going anywhere", despite reports that he will be joining a string of advisers leaving the administration.
But after seven minutes Brighton were ahead.
And it was 2-0 after 26 minutes as Arsenal gave away the simplest of goals. This was not Arsenal being undone by superior skill or speed but failing a test of basic defending. Kolašinac was probably lucky not to pick up a second yellow card.
Just before the break, the Gunners nearly found an undeserved equaliser when Koscielny's header was deflected onto the post, but Brighton were able to scramble the ball away before reaching the interval with their advantage still intact.
The interval came at the right time for Brighton and while the Seagulls didn't develop the same momentum at the start of the second period, they again showed they could stretch the Arsenal defence.
Arsenal had seven minutes of stoppage time to get some points out of the match, and Aubameyang almost did it in the 93rd minute, but his shot went straight at Ryan.
Gross found the back of the net during this period from close range following a cut-back from Murray, but the goal was disallowed as he was flagged for offside.
