Como and Arsenal face different opponents, but both matches revolve around turning a first reception into the next useful attack. Como can vary the point of delivery against a changed United defence. Arsenal bring an established defensive partnership and several outlets against Bayern's pressure.
Como's strongest connection is Douvikas occupying the centre while Paz receives or arrives from another line. Valle's delivery, Baturina's movement and Liberali's involvement give that attack variety. United's supply faded after the interval at Leeds, and their recent lead protection has allowed crosses and second balls to remain dangerous.
Martinez's injury and Yoro's European suspension change United's defensive allocation after both played at Leeds. Como's official squad restores Caqueret's eligibility, preserving the connector who started and assisted against Fiorentina. Fabregas has confirmed Douvikas will start. I expect Como to build repeat attacks through those varied receptions, and that's why I'm siding with Como to win with the draw protected.
In Munich, Kane's deeper passing and Diaz's inside runs meet Arsenal's Konsa–Gabriel partnership and Rice's midfield cover. Arsenal have kept opponents' clear chances limited with those defenders already working together. Their midfield receivers and wide options give them ways to move Bayern back after escaping the first pressure.
Olise is suspended and Kimmich is ruled out by the club-attributed report, after both played the full Leipzig match. That removes distribution and delivery from the latest Bayern attacking display. Arsenal's existing defensive absences were already present in their recent performances, and Zubimendi is available as another receiving option.
I expect Bayern to press early and Arsenal to use combinations, direct forward passes and wide progression to stay involved. The retained Arsenal structure carries more weight for me than transferring Bayern's latest attacking continuity unchanged. That's why I'm siding with Arsenal to avoid defeat.
