In the 36th minute, the Swedes extended their lead to 3–0 and after the home team scored a consolation goal in the 83rd minute, Blackstenius responded with the 4–1 goal a minute later.
Arsenal are fifth in the table with 14 points after seven games played – five behind league leaders Chelsea.
Beata Olsson left Kristianstad in September to play with Liverpool and in the eleventh minute away against Tottenham, the Swede scored her first league goal.
However, there was no victory for bottom team Liverpool. Tottenham – where the blue and yellow trio Josefine Rybrink, Amanda Nildén and Matilda Vinberg started – was able to turn around and win 2–1.
The loss was Liverpool's sixth straight out of a possible six. Fellow jumbo West Ham also have zero points, but have lost seven straight games.
Tottenham are fourth in the table with 15 points.
