Bodo/Glimt continued their remarkable debut Champions League campaign with a 3-1 victory over Inter Milan in the knockout play-off round first leg on Wednesday, as Kasper Hogh scored once and created two other goals.
The Norwegians only snuck into the knock-out stage with shock victories over Manchester City and Atletico Madrid in their final two league-phase matches.
Kjetil Knutsen's men backed up those performances by adding last season's runners-up Inter to their list of scalps.
Cristian Chivu's Serie A leaders will still be confident of turning the tie around in the second leg at the San Siro next Tuesday, despite struggling on the artificial pitch of the Aspmyra Stadion in northern Norway.
"(Bodo/Glimt) are more accustomed to this pitch, that's not an excuse," Chivu said.
"The tie is wide open, there's the return leg to come. We knew they are a team that can hurt you on the break, now we'll try to advance to the next round at San Siro."
To make matters worse for Inter, captain Lautaro Martinez hobbled off and was replaced by Marcus Thuram in the second half.
"I think he's hurt and he will be out for a while," Chivu said of Martinez.
Bodo/Glimt, Europa League semifinalists last term, have given themselves a chance of securing a major surprise, and a last-16 meeting with either Man City or Sporting Lisbon.
The hosts took a 20th-minute lead with a fine team goal, finished off with aplomb by Sondre Brunstad Fet after he latched onto Hogh's clever flick inside the area.
But Bodo could not keep their advantage for long as Inter youngster Pio Esposito swivelled inside the box and fired home on the half-hour mark, with the goal surviving a lengthy VAR review for handball.
Inter almost scored in the first minute after the restart when Martinez's instinctive close-range shot bobbled off the post.
The Norwegians moved back in front in the 61st minute as they caught Inter short at the back and Jens Petter Hauge rifled the ball into the roof of the net after being teed up by Hogh.
Bodo's third goal arrived just three minutes later, as Patrick Berg put Ole Didrik Blomberg through on goal with a cute dinked pass and he squared it for Hogh to tap into an empty net.
From good to great for Bodø/Glimt 🤩🟡

Danish striker Hogh has now scored four goals in his last three Champions League appearances following a double against Man City and the winner to defeat Atletico.
Inter pushed to cut the deficit, but Carlos Augusto's blocked shot from eight yards out was the closest they came despite some late pressure.
