With the Allsvenskan table so tight at the top, it was vital that AIK collected enough points against Falkenberg to keep up with the likes Hammarby, Malmo, and Djurgaarden.
Not only did they collect all three, but did so in emphatic fashion, largely due to the performance of Henok Goitom, who played a part in every goal in their eventual 5-1 victory.
His first two goals came in the first half via a superb glancing header and then a close-range finish at the far post after Falkenberg were put on the back foot after goalkeeper Hampus Nilsson was sent off just nine minutes in.
For the visitors' third, he recorded his assist with a chipped cross to the back post for Tarik Elyounoussi to slam a volley home.
Goitom completed his hat-trick with a rapid spin and finish into the bottom corner, but his fourth was the best of the lot; a magnificent volley looped over the goalkeeper after he shook off his marker to the left of the box.
