Arsenal suffered their fourth consecutive defeat in all competitions as Brighton & Hove Albion took a giant leap towards Premier League survival.
The pressure on Gunners boss Arsene Wenger, which has intensified since the turn of the year, looks set to reach new heights after another dismal day at the office for his charges.
Goals from Lewis Dunk and Glenn Murray put the Seagulls in control before Pierre-Emerick Aubameyang pulled one back for the visitors on the stroke of half-time.
Despite enjoying the lion’s share of possession, Arsenal were unable to muster an equaliser.
For Brighton, this was a huge result that lifted them seven points clear of the relegation zone.
Here are three talking points…
Is beleaguered Wenger’s position now untenable?
It lurches from one disaster to another for Wenger.
He probably thought the nadir had been reached after last weekend’s limp performance in the Carabao Cup final against Manchester City, when his future became the main topic of debate.
The Frenchman would have hoped for a reaction from his players in the subsequent fixtures.
Instead, his side were brushed aside against City in the Premier League before producing another sub-standard display here against Brighton.
Added to their shock Europa League reversal at home to minnows Ostersunds, it is the first time Arsenal have lost four successive matches since 2002.
After last season’s FA Cup triumph, Wenger penned a new contract that takes him through to the summer of 2019.
Now, however, it’s difficult to see how he can last beyond the end of the current campaign.
Perhaps only by lifting the Europa League, which would automatically qualify Arsenal for the Champions League, could Wenger realistically remain in situ.
Even then, it may not be enough. His players look devoid of any confidence and need an injection of new ideas.
Brighton take a massive step towards safety
The focus will understandably be on Arsenal, but Brighton’s display should not be overlooked.
This victory extended their unbeaten run in the Premier League to four games and has all but banished thoughts that they might be dragged into a relegation scrap.
Yes, it was a good time to face Arsenal, but Chris Hughton’s side made a fast start with two early goals that went a long way to recording their first win over the Gunners since 1982.
Brighton’s performance bore all the hallmarks of their season so far.
Despite being one of the lowest scorers in the division, they took their chances when they came, exploiting Arsenal’s weakness from set pieces and aerial balls.
In the second half, the home side remained very organised defensively, which was key when the Gunners upped the tempo.
Modest and unassuming, Hughton has done a terrific job on the south coast.
Defensive shortcomings continue to haunt Arsenal
Wenger has regularly spoken of his belief that Arsenal cannot compete on a level playing field with the likes of Manchester City.
And while his side’s record against fellow ‘Big Six’ clubs is regularly scrutinised, the Gunners’ results against the lesser lights have not been good enough for a club with Champions League aspirations.
In 2018 alone, Arsenal have been beaten by Swansea City, Bournemouth and now Brighton in the Premier League, while losing to Nottingham Forest and Ostersunds in cups.
A lack of leadership has long been an issue on the pitch and it’s an area Wenger has consistently ignored.
Defensively, the Gunners are too easy to bully.
Take Shkodran Mustafi’s defending for the first goal in the Carabao Cup final last weekend, for example.
Particularly away from home, Arsenal are prone to imploding.
Despite the attacking talent Wenger has at his disposal, his failure to invest in proven defenders at the top level looks set to cost him dearly.
