IBK against JKJ is a group decider between two sides whose best weapons hit each other's weakest spots, so the sets should swing on serve runs rather than one team controlling every set. In Phnom Penh, Svay Rieng want to play and press at home, and that suits a Shenhua side that wins games by the number and variety of chances it creates rather than by keeping the ball. Both matches turn on a real mismatch in content, not on names or last season's tables.
IBK under new coach Manabe have not settled their starting unit. Against Hungkuk, the Park Eun-seo and Victoria pairing started badly: Victoria hit 36% and was taken off, and IBK dropped the first two sets before Kim Ha-kyung came in at setter and they took the next two. JKJ have no foreign main hitter for the cup, but their serve and block are genuinely sharp (8 aces and 8 blocks against SOOP), and they took the opening set off Hungkuk 25-18. Against that same Hungkuk side, IBK were only four points better over five sets and JKJ six points worse over four, so the gap is smaller than the names suggest.
The key matchups run both ways. IBK's serve against JKJ's reception, which wobbled late in sets against both SOOP and Hungkuk, is IBK's route, and it usually wins them sets. JKJ's serve and block against IBK's unsettled setter unit is their route, and Zhong Hui carries their scoring. Im Myung-ok's return as libero helps IBK, but JKJ only need one serve run and one held lead. The likeliest shapes are four or five sets, and a clean IBK sweep needs JKJ's reception to fail in every set. That's why I'm siding with JKJ to take at least one set.
In Phnom Penh, Shenhua's rotated XI already out-shot Tampines 20 to 5 in their opener, with chances from midfield carries, wide cut-backs, high turnovers and second balls after set plays. None of that depends on who starts. Svay Rieng managed two shots on target and no goals across two continental games, conceded eight, and are reported to be without centre-back Sareth Krya, who also scores from set plays. Their coach has said he won't park the bus, which opens space behind for Shenhua's vertical attacks.
The home side will start with crowd energy, and Shenhua arrive after an overnight flight into humid conditions, so a slow first quarter-hour is likely. As Svay Rieng commit players, Shenhua's chances should grow, and once the first goal comes the hosts have to open up further, as they did against JDT. That's why I'm backing Shanghai Shenhua to win away.
