Djurgarden, eleventh in the table before the match, came into the derby with five losses in the last six games.
But there was no sign of nervousness. Dif was scorching hot in the first period and washed over AIK. 13-2 in shots and 2-0 in goals in the first period spoke for itself.
Djurgården's Anton Gradin scored his second goal of the season, which was also the second goal of the game – which would prove decisive.
"It's really fun, it's always fun to be involved and contribute. Awesome, says Gradin.
In front of 13,250 people in Avicii Arena, AIK reduced the deficit to 1-2 but didn't get any closer than that. 3-1 for Djurgården came in an empty bag.
"We're trying to get a push, unfortunately we can't get the puck in. Of course, sour right after, says AIK's coach Anton Blomqvist.
