Arsenal had pegged themselves back from being behind twice before Iman Beney’s dramatic late winner at Joie Stadium.
It extended City’s winning streak to four WSL matches – their best run of form since November 2024.
It was also City’s first victory over Arsenal in the WSL since February 2023, having gone five games without a win against the European champions.
While Arsenal have dropped seven points from a possible nine in their past three games, City have quietly and efficiently gone about their business.
“Of course I’m happy with the result. The game was won by us keeping on believing,” said Jeglertz.
“Even when they made it 1-1, then 2-2, the team was still believing that we would create more goalscoring chances.
“There was no player thinking ‘oh, now we need to protect this result’. That will not happen in this group. That belief is a key thing.
“The team is showing when they have setbacks – they conceded two goals – that they don’t do their own things, they just keep going.”
It has perhaps been a stick poked at City in previous seasons – that they don’t have the bite or ruthlessness of six-time successive champions Chelsea.
They looked stale and rigid at times, playing a well-drilled style of possession-based football from the days under former manager Gareth Taylor.
But Jeglertz has added a sprinkle of unpredictability and adaptability since his arrival in the summer.
Pushing midfielder Yui Hasegawa further up the pitch has delivered excellent results, while his attackers play with fluidity across the frontline.
Full-back Kerstin Casparij played more advanced against Arsenal and Khadija Shaw received the ball in the middle, where she is most damaging.
“For me it’s about making sure we keep the Manchester City identity of being possession-based, but it is first of all about scoring,” said Jeglertz.
“In these last few games we have created a lot of goalscoring chances. That always has to be the priority.
“It’s about finding the ways to maximise each player. That is my biggest philosophy. I hope and I think the players feel that.
“I still think we are in a process but it’s important to win while you’re in a process also.”
