It can be considered a prediction of the team that will appear in the final round is Bilbao vs Bodø/Glimt. I would bet on Bilbao if the scheme was like that the team in the Final.

Bodø/Glimt beat Lazio when Bodø/Glimt very few believed they could beat Lazio.
Uniquely if the scenario is Lazio vs Bodø/Glimt, then these two teams are able to reach the final without relying on players from other countries. If Bodø/Glimt's line up when they eliminated Lazio only had 2 players from outside Norway, Bilbao's players were all from Spain.
