Kasper Hogh's delicate chip got the Norwegian team off to a flyer before Odin Bjørtuft doubled the advantage moments later with a header and Ulrik Saltnes' turn and finish made it 3-0 after 25 minutes. The hosts kept coming after the break, Håkon Evjen's strike and a William Boving own goal capping a stunning performance which leaves Sturm requiring a second-leg miracle.
