The Norwegian Eliteserien 2015 season is just a couple of months old but Mjøndalen and Tromsø may have played out the best encounter of the campaign.
Tromsø took control of the game in the first half with goals from Gjermund Åsen and Zdenek Ondrášek.
Gauseth Christian pulled a goal back for Mjøndalen from the penalty spot but Tromsø went 3-1 up through another goal by Ondrášek.
The Mjøndalen fightback got going at 3-1 down with 72 minutes played. Christian Gauseth pulled one back from a scrappy corner.
Then Rhett Bernstein took over, winning the game for Mjøndalen.
The American defender nipped in for the equaliser on 74 and then won the match on 90 with a back post header to spark wild scenes.
