Frida Maanum’s superb strike kept Arsenal in the hunt for a finish in the top three of the Women’s Super League as they edged Leicester.
Maanum broke the visitors’ resistance midway through the second half with a fine curled finish from distance.
But they finished strongly and Norwegian Maanum struck the crossbar late on with a free-kick.
Leicester, fighting to stay in the WSL, had few chances but Sam Tierney saw a good header held by Sabrina D’Angelo before Arsenal struck.
The result means Arsenal stay fourth, but are now just two points behind third-placed Chelsea, who have a game in hand.
Leicester, meanwhile, are 10th, two points off the bottom of the table.
