The last time the teams met in the European Games, Djurgården won 3-2.
But in the return in Norway, Molde, who with three rounds left in the Norwegian league have already secured the title, had a dream start.
Already in the sixth minute, the home team took the lead when Ola Brynhildsen got free in front of Djurgåden's goal and put the ball between the legs of Jacob Zetterström.
A quarter of an hour later, Markus Kaasa extended Molde's lead and suddenly things looked heavy for Djurgården.
But the turn would come.
In Djurgården's first real chance came the reduction.
Gustav Wikheim made his way towards the penalty area and played deliciously forward to Victor Edvardsen who angled the ball into the goal.
In the second half, it was Pierre Bengtsson who answered for the assist.
The left back received a ball in deep and hit a cross that Joel Asoro met perfectly with his forehead to make it 2-2.
The turnaround was then completed through Haris Radetinac.
The 36-year-old - oldest on the pitch - held off his defender and fired in 3-2 - a perfect way to celebrate his 37th birthday a day early.
- It's nice, my first goal in the group stage, says Radetinac.
The victory, Djurgården's fourth in a row in the Europa Conference League, means that they secure first place in group F and thus take the shortcut in the playoffs - as a group, they avoid the round of 16 and instead go directly to the round of 16, which will be played in March.
- That was our goal, we wanted to win the group and we succeeded in that today, says Radetinac.
On Thursday, November 3, Djurgården will face Shamrock Rovers in the last group stage match.
Before that, Norrköping awaits in the penultimate round of the Allsvenskan on Monday.
