Having started the season under new boss Andree Jeglertz with a narrow 2-1 defeat by Chelsea, City knew they had to make up ground to mount a title challenge.
Defeating another key rival in Arsenal was the perfect way to do so and they have closed in on Chelsea as a result, sitting just one point behind having each played five games.
What will be even more pleasing is the manner in which City took their chances at key moments, capitalising on a period of first-half pressure before responding to Arsenal's early second-half equaliser, and again with minutes to spare.
They were the side who looked in control for larger periods and created more dangerous opportunities, often pushing Arsenal's backline into mistakes.
Shaw was at her best, causing problems with her devious runs in behind and presence in the box, while Aoba Fujino was lively down City's right-hand side.
It was also another impressive showing from full-back Kerstin Casparij - she is quickly becoming one of the most influential players in the WSL.
There will be concern as to how City allowed Arsenal back into the game twice, but given the high stakes in matches between the WSL's top four, it won't bother them much.
