Ulsan's recoveries and quick service meet Seoul's occasionally disconnected final pass. Hiroshima's wide combinations face Machida's pressure and an accomplished goalkeeper behind it. In each match, reaching the next receiver matters more than the recent scoreline alone.
Cho Hyun-taek and Lee Dong-gyeong have supplied Ulsan's forwards through recoveries, interceptions and deliveries. Erik gives them another receiver after changes from the bench. Seoul can answer through Babec, Son Jeong-beom and Choi Jun, with some central roles rested during the continental fixture. Lee Seung-mo's doubtful status is not a required premise, and the recent Ulsan roles are projections from their actual use rather than an announced lineup.
The interval and attacking substitutions are important because both coaches have recently altered the connections with direct effects. Ulsan's service gives them a way to respond without needing to control possession throughout. That's why I'm siding with Ulsan HD to avoid defeat.
Hiroshima can work through Nakano and Arai on the right, with Higashi, Suga and Matsumoto supplying other angles. Machida's recent low concessions have included meaningful opposition chances, Tani saves and a goal-line clearance. Hiroshima's injured central and midfield roles were already absent from the latest squad, so the judgment rests on the replacements and supply that remain. Machida rested several attackers for part of their continental match, while supporting and covering players carried starting workloads.
I expect Machida's opening pressure to give way to a more sustained contest over second balls and repeat attacks. Hiroshima's longer recovery helps them keep supporting those established wide routes. That's why I'm siding with Sanfrecce Hiroshima, with a draw returning that selection.
