Arsenal's defence of the Premier League title has started almost perfectly. Four matches, four victories and only one league goal conceded.
But Saturday's trip to the Amex Stadium could provide Mikel Arteta's champions with their most intriguing test yet.
Brighton have scored 13 Premier League goals in four matches — the highest total in the division — while Arsenal have conceded only once. It creates a fascinating battle between the Premier League's most productive attack and one of its strongest defences.
For Arsenal, victory would mean five wins from five and strengthen an early title defence that has already separated them from several traditional rivals.
It also provides another chapter in a question we examined before the season began: Can Arsenal defend their Premier League title?
So far, the answer from Arteta's players has been emphatic.
Arsenal's Perfect Premier League Start
Arsenal arrive on the south coast with 12 points from a possible 12.
Their most recent league victory came at Sunderland, where David Raya saved a penalty before Bruno Guimarães opened the scoring and Bukayo Saka converted a stoppage-time penalty to complete a 2–0 win.
That result maintained Arsenal's 100% Premier League record.
Even more impressively, the champions have continued winning during a demanding sequence away from the Emirates.
Saturday will be Arsenal's fourth consecutive away match following victories at Napoli in the Champions League, Sunderland in the Premier League and Ipswich Town in the League Cup.
Arteta believes his side must demonstrate that its identity does not change according to the venue.
That mentality will be tested at Brighton.
Brighton Present a Very Different Challenge
Looking only at Arsenal's perfect record would underestimate Saturday's opposition.
Brighton enter the match with the Premier League's most prolific attack through four rounds.
They have scored 13 league goals, and their confidence should be even higher after an extraordinary midweek comeback at Old Trafford.
Brighton trailed Manchester United 2–0 after only 10 minutes in their Carabao Cup meeting before fighting back to win 3–2.
Charalampos Kostoulas pulled one back before half-time, Pascal Groß equalised and Maxim De Cuyper completed the comeback.
It was a historic collapse for United — something we recently examined in our coverage of Manchester United's 3–2 Carabao Cup defeat to Brighton.
For Arsenal, that result should serve as a warning.
Brighton have already demonstrated that even when a match appears to be moving away from them, they possess enough attacking quality to change it.
The Key Battle: Brighton's Attack vs Arsenal's Defence
This could be where Saturday's match is decided.
Brighton: 13 Premier League goals scored.
Arsenal: one Premier League goal conceded.
Arteta's team have built their title defence around control and defensive security, but Brighton are unlikely to spend 90 minutes simply protecting their own penalty area.
Fabian Hürzeler's side want to attack.
They will attempt to move Arsenal's defensive structure, create overloads and force the champions into uncomfortable situations.
Arsenal, meanwhile, will want to control possession, reduce Brighton's transitions and use players such as Bukayo Saka to attack spaces when the hosts commit numbers forward.
It makes this much more than a routine away fixture.
Arsenal Have Defensive Decisions to Make
Arteta still has several fitness decisions before naming his team.
Jurrien Timber, Ben White, Cristhian Mosquera and Piero Hincapié missed Arsenal's midweek League Cup victory at Ipswich.
Arteta confirmed on Friday that all four were due to be assessed during Arsenal's final training session before the Brighton match.
Their availability could be particularly important given Brighton's attacking form.
Arsenal have conceded just once in their opening four league matches, and maintaining that defensive standard will be critical at the Amex.
The champions cannot afford to allow Brighton the type of momentum Manchester United surrendered on Wednesday.
Arteta and Hürzeler Put Previous Controversy Behind Them
There is also history between the two managers.
When Arsenal visited Brighton in March, Hürzeler criticised Arsenal's tactics after the match, accusing Arteta's team of wasting time while taking corners.
The Brighton manager subsequently apologised to Arteta by text.
Arteta made clear on Friday that the incident is finished and spoke respectfully about both Hürzeler and Brighton.
That removes some of the personal tension from Saturday's encounter, but the competitive stakes remain significant.
Arsenal know Brighton can cause problems.
Brighton know defeating the champions would make a major statement about their own start to the campaign.
Bukayo Saka Could Be Crucial Again
If Arsenal need someone to make the difference, Bukayo Saka remains an obvious candidate.
Saka scored from the penalty spot against Sunderland and continues to carry enormous responsibility in Arsenal's attack.
His ability to isolate defenders, create chances and score in important moments gives Arteta a weapon capable of changing tight matches.
Brighton's willingness to attack could potentially create opportunities for Saka in transition.
If Arsenal can beat Brighton's initial pressure and quickly move the ball into wide areas, the England international could find the type of one-on-one situations where he is most dangerous.
Arsenal's evolution under Arteta has increasingly been about combining defensive control with individual attacking quality.
Saturday should provide another examination of that balance.
Why Victory Would Matter Beyond Three Points
Five victories from the opening five Premier League games would not win Arsenal another championship in September.
But it would reinforce the message that last season's title was not the end of something — it was potentially the beginning.
Manchester City have also opened the league season with a perfect record, while several other major clubs have already dropped points.
That makes every opportunity to maintain momentum valuable.
We have already seen how quickly the title conversation can change. Earlier this season we examined whether Chelsea could really challenge for the Premier League, but dropped points have already altered the early picture.
Arsenal's job is to avoid the same problem.
The champions have created an excellent platform.
Now they must protect it.
Brighton vs Arsenal: What to Watch
The most important question is whether Brighton can turn the match into an open contest.
If they can, their attacking form gives them a genuine opportunity to trouble Arsenal.
If Arteta's side controls possession, slows Brighton's transitions and forces the hosts to defend for extended periods, Arsenal's quality should become increasingly difficult to contain.
There is also the issue of fatigue.
Arsenal are entering their fourth consecutive away match, while Brighton arrive following an emotionally and physically demanding comeback at Manchester United.
Who manages those demands better could become increasingly important during the second half.
The official Premier League fixture is scheduled for Saturday, September 19 at 3:00 p.m. BST at the American Express Stadium.
Final Thoughts
Arsenal could hardly have asked for a better beginning to their Premier League title defence.
Four games. Four victories. Twelve points.
But Brighton represent something different.
The hosts possess the league's most productive attack, enter the game with confidence after their remarkable comeback at Manchester United and have already shown they are capable of turning chaotic matches in their favour.
For Arsenal, this is therefore another opportunity to demonstrate why they are champions.
Winning comfortably is impressive.
Winning difficult away matches when the opposition is confident, dangerous and determined to attack is often what separates champions from challengers.
Beyond the Final Whistle, Brighton vs Arsenal looks like one of the most fascinating tactical battles of the Premier League weekend. The league's highest-scoring attack meets a defence that has conceded only once — and something has to give at the Amex.
Can Arsenal make it five Premier League victories from five, or will Brighton become the first team to stop the champions this season? Join the conversation on Beyond the Final Whistle.
