Arsenal squandered several scoring opportunities on the artificial turf of the Bravida Arena, and their lack of precision in front of goal came back to haunt them. Tindell capitalized on a counterattack with just 13 minutes remaining, calmly slotting the ball past Manuela Zinsberger to secure a victory for the hosts and extend their unbeaten streak at home to three months.
However, Jonas Eidevall will be wondering quite how his side left his homeland without scoring after the visitors passed up numerous openings on the night as first summer signing Rosa Kafaji crashed an effort off the bar against her old club.
Meanwhile, after the break BK Hacken captain Jennifer Falk produced a word-class stop to somehow keep out Beth Mead's point-blank header, albeit the Sweden international did not know much about it, before substitute Frida Maanum's injury-time header also hit the crossbar.
Eidevall, though, will be confident his players will be able to finish off the job when the two sides meet again in the return leg at Meadow Park on Thursday September 26, with the winners progressing into the group stage of the competition.
