Liverpool can start quickly through a recovery and a Barcola delivery to Isak. Arsenal have the midfield passing to play through that first press and create a different kind of chance. Juventus can use their midfield runners and restarts against Napoli's central cover. Napoli's wide deliveries have several receivers and can answer a home spell of possession.
At Anfield, Rice and Odegaard's line-breaking passes test Liverpool's midfield before Wirtz and Barcola can turn the ball forward. Liverpool's direct Isak connection is real, but Arsenal's back line has restricted repeated accurate shots, and Konsa completed a full match in the replacement role. Saka is out and Madueke's role is unsettled, so Arsenal's case rests on those central passes, Eze or the striker, and the later Rice arrival. That's why I'm siding with Arsenal.
Against Juventus, Napoli can move through Di Lorenzo and Politano toward Højlund, Lang and McTominay's far-side run. Lobotka left the previous match early, but Gilmour then played most of it and Napoli still reached the box often; Politano's recent delivery and finish are observed rather than assumed from a squad listing. Juventus have Douglas Luiz and McKennie arrivals, yet their recent forwards have produced few accurate finishes. Napoli's surviving wide supply and separate box receivers carry this matchup. That's why I'm siding with Napoli.
