The fourth matchweek of the 2026/27 Women’s Super League season saw Chelsea beat Arsenal at Stamford Bridge, while Manchester City maintained their perfect start.

Alyssa Thompson scored the only goal of the game as Chelsea claimed a 1-0 victory over their London rivals, leaving Arsenal seven points behind the league leaders just four matches into the campaign.

Manchester City remain the only side with a 100 per cent record, while Chelsea moved up to third after extending their unbeaten WSL run to 12 matches.

Elsewhere, Tottenham Hotspur continued their strong start, while several other sides picked up important results as the table began to take shape.

Here’s how the action unfolded across Matchweek 4.

Chelsea 1-0 Arsenal: Alyssa Thompson Decides Stamford Bridge Clash

Chelsea secured a 1-0 victory over Arsenal at Stamford Bridge with Alyssa Thompson’s first-half goal enough to settle a feisty London derby.

The result continues Chelsea's unbeaten start to the season and leaves Arsenal still searching for consistency in attack.

Arsenal had plenty of the ball and registered 19 shots across the game, but only two were on target.

That lack of accuracy ultimately proved costly.

Chelsea were not at their most fluid in possession and Arsenal spent long periods controlling the territory, but Sonia Bompastor’s side defended with discipline and were able to take advantage when their opportunity arrived.

The decisive moment came late in the first half.

Keira Walsh unleashed a powerful effort which Anneke Borbe could only parry, with Thompson reacting quickest to the loose ball before firing into the roof of the net.

It was a decisive finish from the USA forward and gave Chelsea the platform they needed.

Arsenal pushed for an equaliser after the break, but Chelsea remained organised and frustrated their opponents.

Bompastor’s side were also able to threaten on the counter, with Melvine Malard going close to adding a second.

In the end, Chelsea did not need another goal.

The victory came with Chelsea missing several players through injury, while Lauren James returned to the squad and Walsh featured despite being forced off during Chelsea’s Champions League fixture earlier in the week.

For Chelsea, it was a result built around defensive organisation and taking their biggest opportunity.

Liverpool 2-0 Everton: Reds Win Merseyside Derby

Liverpool also claimed a 2-0 victory over Everton in the Merseyside derby.

The result gave Liverpool an important victory in the local derby and added another positive result to their campaign.

For Everton, the defeat was a setback after making a strong start to the season.

Liverpool's victory gives the Reds three points as the league table begins to take shape.

Birmingham City 3-3 Crystal Palace: Six-Goal Draw

There was no shortage of entertainment at St Andrew’s, where newly promoted Birmingham City drew 3-3 with Crystal Palace.

The two sides traded goals throughout an open contest, with neither able to find the decisive seventh goal.

For Birmingham, the point adds another encouraging moment to their first season back in the WSL.

Palace will also take positives from their attacking display, although conceding three goals will leave them wondering what might have been.

The six-goal draw was one of the weekend's most entertaining fixtures and highlighted the competitiveness across the WSL.

Manchester United 2-1 West Ham: First WSL Win of the Season

Manchester United finally claimed their first WSL victory of the season after beating West Ham United 2-1.

Elisabeth Terland and Andrea Medina scored for Eva Olid’s side, who had been waiting for their first league win after an inconsistent opening to the campaign.

It is an important result for United, particularly after their difficult opening weeks.

Olid can now build from a first league victory as United look to climb the table and establish some consistency.

London City Lionesses 2-0 Brighton: Putellas Scores First WSL Goal

Alexia Putellas also had a weekend to remember.

The two-time Ballon d’Or winner scored her first WSL goal for London City Lionesses in their 2-0 victory over Brighton.

Putellas opened the scoring in the 29th minute before Lucia Corrales added a second in stoppage time.

The victory moved London City into second place and highlighted the attacking quality available to Eder Maestre's side.

For Putellas, the goal was a significant personal milestone.

After arriving in England during the summer, she now has her first league goal and another important contribution to a London City side competing near the top of the table.

Tottenham 4-0 Aston Villa: Spurs Move Second

Tottenham Hotspur also continued their strong start to the campaign with a 4-0 victory over Aston Villa with summer signing Victoria Pelova scoring twice.

Spurs' latest win keeps them near the top of the WSL table and underlines their attacking form.

With Manchester City still perfect and Chelsea now applying pressure, Tottenham’s strong start gives the league another potential challenger to watch.

Charlton 0-1 Manchester City: Greenwood Keeps Champions Perfect

Manchester City remain the only team with a perfect WSL record after beating Charlton Athletic 1-0.

Alex Greenwood’s free-kick was enough to secure a fourth consecutive league victory for Andrée Jeglertz’s side, who remain top of the table.

That makes Arsenal’s defeat to Chelsea even more significant.

City have already created early breathing room, while Chelsea are continuing to collect points and London City and Tottenham are keeping themselves within touching distance.

Arsenal, meanwhile, now face a huge test.

Their next league fixture is against the unbeaten leaders, meaning the Gunners have an immediate opportunity to respond, but another dropped result would leave them with even more ground to recover.
