Brighton & Hove Albion's impressive unbeaten run drew to a close at Anfield on Sunday, as two quick fire first-half strikes from the home side proved to be the difference at the final whistle. 

Missed chances, injuries and tactical decisions left Fabian Hürzeler on the losing side for the first time in 8 games.

After four consecutive Premier League victories without conceding, Brighton & Hove Albion were brought back down to earth following a 2-0 defeat against Liverpool.

A Pascal Groß own goal and an Alexander Isak finish within four first-half minutes proved costly, ending the Seagulls' impressive winning streak.

Despite enjoying the majority of possession and registering more attempts than their opponents, Albion couldn't find a breakthrough.

Here are five things we learned from a frustrating afternoon up North.

How different could this match have been if Yasin Ayari had taken his early opportunity?

With the score still goalless, Diego Gómez and Groß combined brilliantly to create an opening for the Swedish midfielder.

Alisson was vulnerable, the goal was inviting, but Ayari blazed his effort over the crossbar.

Minutes later, Liverpool were ahead.

The Swedish midfielder came close to redeeming himself when his curling effort struck the post later in the first half, but it ultimately summed up Brighton's afternoon.

Plenty of promising attacking situations, but no end product.

After scoring 23 goals in their opening seven league fixtures, Brighton's attacking efficiency had been one of their greatest strengths.

However, Sunday's performance demonstrated that creating opportunities means very little if you cannot convert them. 

Against the Premier League's strongest sides, clear-cut chances are often limited. 

Ayari's miss wasn't the sole reason for the defeat, but it was undoubtedly a defining moment.

There is no denying that Fabian Hürzeler's aggressive approach has produced some outstanding performances this season.

However, Sunday's defeat raised an important question: Is playing such a high line away against multi-million pound attacks always worth the risk?

Liverpool possess talent capable of exploiting even the smallest spaces, and Brighton's willingness to push forward left them vulnerable when possession was lost.

The opening goal came after Florian Wirtz's effort deflected off Groß and beyond Bart Verbruggen.

While the deflection was unfortunate, Brighton had struggled to deal with Liverpool's attacking pressure in the build-up.

Four minutes later, the hosts doubled their advantage.

Bradley Barcola blocked Olivier Boscagli's attempted clearance before driving forward and finding Isak, who finished clinically.

Once again, Brighton were punished after losing possession in a dangerous area.

Hürzeler's philosophy relies on pressing aggressively and maintaining a high line to keep opponents under pressure and when it works, Brighton dominate matches and overwhelm teams.

But, against elite opposition, particularly away from home, the margins are often smaller. 

We saw a similar outcome at Stamford Bridge in August, where Chelsea found themselves 3-0 up in just over 30 minutes thanks to individual brilliance and quick-fire counter attacks.

Liverpool have the pace, movement and technical quality to exploit space behind defenders, making Brighton's approach dangerous when pressing isn't perfect.

Hürzeler should not abandon his principles, however, the debate whether there needs to be greater tactical flexibility, especially in games like this, should not be ignored.

The best teams know when to press aggressively and when to recognise danger. 

If Brighton want to compete with the Premier League's elite in their own backyards, learning the balance will be essential.

Brighton's afternoon became difficult when Ferdi Kadıoğlu was forced off with an injury after just six minutes. 

The Turkish international has become a huge part of Hürzeler's setup, offering versatility, quality and experience.

His early departure forced a reshuffle, with Costinha introduced  earlier than anticipated.

The situation worsened when Chema Andrés was also forced off shortly after half-time.

The midfielder had shown energy and determination, particularly when pressing Liverpool.

His departure deprived Brighton of another player capable of disrupting the opposition's build-up.

With two fixtures against Manchester City approaching, the timing is far from ideal.

Brighton's squad depth has been one of the biggest positives this season, particularly during their European campaign.

However, losing important players during matches can disrupt tactical plans and limit options. 

The hope will be that neither injury proves serious.

If there was one thing Sunday’s result demonstrated, it’s that Liverpool remain a problem. 

Not just for Brighton, who have a poor record at their home ground, but for the rest of the League too.

And they’ve now passed a test that’s become something of a running joke on social media.

The ‘Three Bs’ (Brighton, Bournemouth and Brentford) have developed a reputation for causing problems for the Premier League’s biggest clubs.

Fanbases have voiced that these are the fixtures capable of derailing a title challenge, cup run or champions league charge, regardless of how well a team is playing.

Yet Liverpool have now beaten all three this season.

While this might sound like a silly trend, it highlights the Reds’ ability to navigate fixtures that have become difficult in recent seasons.

With the attacking quality of Alexander Isak, Florian Wirtz and Bradley Barcola, alongside the experience throughout their squad, Andoni Iraola has the tools to mount a challenge for silverware this season.

Beating the ‘Three Bs’ won’t win Liverpool a title,  but overcoming the teams capable of upsetting the biggest names is what the real challengers do.

After last weekend's 5-0 victory over Crystal Palace, expectations surrounding Brighton were understandably high.

Thanks to that win and the extraordinary start to the 26/27 campaign, the Seagulls had established themselves among the Premier League's early frontrunners.

Sunday's defeat was disappointing, but perspective is essential.

Anfield remains one of English football's most difficult venues, and Liverpool possess attacking players capable of punishing even the smallest mistakes.

Brighton weren't at their best, but still created opportunities and demonstrated a willingness to compete.

More importantly, this was only their second Premier League defeat of the campaign.

Victories over Aston Villa, Arsenal and Palace have already shown the quality within the squad.

One disappointing afternoon doesn't erase those performances. 

However, the manner of defeat should provide a useful reminder that Brighton remain a developing side.

The defensive scares, missed opportunities and lack of attacking efficiency all highlighted areas requiring improvement.

With Manchester City awaiting twice in four days, the response will be important.

The challenge isn't returning to winning ways, It's demonstrating that Brighton can learn from setbacks and adapt when their usual approach isn't working.

Brighton's defeat at Anfield was frustrating, particularly given the opportunities they failed to convert.

But there were also lessons worth taking forward.

The Seagulls have demonstrated an ability to produce outstanding football this season, and now they must show they can combine quality with  defensive discipline and clinical finishing.

One defeat doesn't define Brighton's season. How they respond to it might.
