PSG and Barcelona have ways to reach the box from both a clean first pass and a recovered clearance. A goal could push the chasing side to commit more players forward and create another chance from the far side. Napoli and Bodø/Glimt will also test each other's first outlet. Napoli can own territory, while Bodø/Glimt's central connection can turn a regain into a quick wide attack.
PSG can press Barcelona's changed defensive outlet, return a blocked shot and feed Dembélé or Doué before the line resets. Barcelona can break that wave through Rodri and Pedri and find Yamal, Raphinha or the far-side runner against PSG's changed left side. Koundé and Eric García played against Betis but are now out of Barcelona's travelling group, and Mendes played against Strasbourg before PSG confirmed his absence. Both clubs have shown ways to keep supplying the box after conceding, so I'm siding with the scoring to keep building in PSG against Barcelona.
Bodø/Glimt's Berg, Auklend and Fet can interrupt Napoli's first connection and release Hauge or Sjøvold into space. Napoli have De Bruyne and Højlund as earlier targets, but their recent box volume has not consistently become a second clean finish, and Alisson's injury after playing Venezia removes a late wide option. Blomberg left HamKam injured, though Mvuka scored there and offers another active receiver. Bodø/Glimt's pressure and quick outlets are why I'm siding with them to stay close to Napoli.
