Ireland captain Katie McCabe claimed the bragging rights over international team-mates Niamh Fahey and Megan Campbell as Arsenal beat Liverpool 2-0 in the Women's Super League.
McCabe's Arsenal side equalled the WSL record of 12 consecutive victories as they eased to victory at Prenton Park.
The Gunners bossed the first half, scoring through Lia Walti and Frida Manuum, and though their threat faded after the break they had done enough for a fifth straight win in all competitions and 10th away from home against Liverpool.
It means Arsenal equalled the wins record they set in 2018, matched by Manchester City in 2021, and Jonas Eidevall's side have now scored at least two goals in 11 of their last 12 matches.
Eidevall chose to stick with the same 11 who made a statement with a 5-1 rout of European champions Lyon in midweek - perhaps no surprise but that did mean another seat on the bench for star forward Vivianne Miedema as Manuum kept her place.
But though Liverpool made a bright start in front of a record crowd of 3,348, Eidevall's decisions were soon justified.
Campbell's block denied Beth Mead a sixth goal of the season before Stina Blackstenius' cross narrowly missed Caitlin Foord's outstretched toe.
But Arsenal led in the 14th minute as Steph Catley's corner was only half-cleared and Walti hit a fine strike through the crowded penalty box.
It was 2-0 in the 23rd minute as Manuum showed her strength, shrugging off two defenders before powering a shot past Rachael Laws from close range.
Liverpool were on the ropes, and two minutes later Foord cut in from the left and hit a shot which found the outside of the far post.
Liverpool, yet to score from open play this season, kept battling but struggled to create openings, lacking both the pace and the precision to open up Arsenal.
Their best chance came when Catley blocked Taylor Hinds' low cross and was relieved to see the ball bounce just wide of the post after looping up and past the helpless Manuela Zinsberger, and the half ended with Kim Little blazing over for Arsenal.
The hosts looked most dangerous from set pieces, with Irish defender Fahey going close with a header from a second-half corner and then following that up with a shot that flew just wide a minute later.
Having threatened every time they went forward in the first half, Arsenal were more muted after the break as Liverpool enjoyed more time on the ball, but Laws needed to make a good save from Foord after Mead drove forward just after the hour.
Eidevall sent on Miedema 13 minutes from time but the final chance fell to Mead, denied by Laws from close range in stoppage time.
Nikita Parris' deft header ensured Manchester United remain locked together with Arsenal at the top of the table.
The 28-year-old glanced home Katie Zelem’s first-half free-kick to secure a 1-0 victory at lowly Leicester, although her England international team-mate Mary Earps had to make two important second-half interventions to deny the hosts a way back into the game at the King Power Stadium.
United, however, sit in second place in the table by virtue of alphabetical order with they and the Gunners boasting identical records of 12 points, 11 goals for and none against after four games.
Chelsea had to work hard to keep pace with the top two, whom they trail only on goal difference having played a game more after a 2-0 win at Brighton.
The much-changed champions endured a frustrating evening for long periods after seeing first-half penalty appeals for Victoria Williams' challenge on Jessie Fleming waved away and Beth England’s 47th-minute strike ruled out for offside with Seagulls' Irish keeper Megan Walsh standing firm.
They finally got their noses in front when England tapped home after Niamh Charles' 58th-minute shot had hit the underside of the crossbar, and substitute Pernille Harder made sure of the points with a second four minutes from time.
Striker Viviane Asseyi’s first-half double set West Ham on their way to a 3-2 home victory over Reading.
Iceland international Dagny Brynjarsdottir headed the home side into a fourth-minute lead before Asseyi struck after 22 and then 29 minutes to give her side a commanding half-time advantage.
Charlie Wellings pulled one back for the visitors with 15 minutes remaining and their faint hopes received a further boost when substitute Sanne Troelsgaard converted an 82nd-minute penalty following Kate Longhurst’s foul on Rachel Rowe, although it all proved to no avail.
Izzy Atkinson came on for the winners as an 80th-minute substitute.
