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.

But Bodo/Glimt, Europa League semi-finalists 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.
