A ninth victory of the campaign and seventh clean sheet will please Arsenal boss Renee Slegers.
Despite being without Steph Catley and Caitlin Foord, who are both currently representing Australia at the Asian Cup, they barely had to get out of second gear to overcome London City.
The hosts tried to make an impression but their positive moments were scarce, limited to attempting to attack Arsenal without being able to produce much at the end of their moves.
There were some good signs for London City when players began to come off the bench, but they remained firmly second-best.
Tricky conditions on Sunday had an impact on the game, with strong winds making long balls unpredictable and neutering any attempts to create trouble in the air from set-pieces.
The lack of recent league football, with no WSL games having been played in the past month following FA Cup action and an international break, will also have stunted Arsenal’s momentum.
Winning in a convincing fashion given those factors is promising, although the Gunners will likely feel the margin of victory should have been more comfortable.
They had 12 shots, but only hit the target with the two that resulted in goals. They controlled the ball, having 58.5% possession, but were unable to find a way to translate that into causing too many issues for Lete in the home goal.
While this was far from their best display, getting back to form as the end of the season approaches was important.
They do not have to play any of the top three left in league action and have two games in hand on leaders Manchester City, who are 11 points clear of them. The title is all but mathematically out of their reach, but qualifying for Europe is in their hands.
