Nicklas Bendtner inspired Denmark to victory against Scandinavian rivals Norway to leave Euro 2012 qualifying Group H fascinatingly poised.
The striker, loaned from Arsenal to Sunderland ahead of last week's transfer deadline, scored twice in the first half, the second a superb long-range effort.
The win brings Denmark level on points with group leaders Portugal and Norway, who have just one game remaining compared to their rivals' two.
Meanwhile, Iceland finally claimed their first win of the Euro 2012 qualifying campaign as Kolbeinn Sigthorsson's strike saw off Cyprus.
Sigthorsson netted after four minutes and that was the way it stayed, meaning Cyprus replaced their hosts at the foot of the group.
Iceland burst out of the blocks and grabbed the lead early on when Johann Berg Gudmundsson played in Sigthorsson to finish from 12 yards.
