Kobe can hold the ball high and keep sending crosses and second balls into the area. Ratchaburi can spend long spells defending close to its box and look for a direct release after a clearance. The first goal will change the space, but the next clean finish will decide how wide the result becomes.
Kobe's wide service, Komatsu and its late substitutes have produced important goals, yet recent large scorelines included an own goal and a late addition. Against Daejeon, Kobe needed a late cross to win after allowing plenty of opposition shots. Ratchaburi's compact central defence and Kampol helped hold Kashiwa despite repeated entries. Kobe's coach has announced changes without naming them; the main attackers played against Nagoya, while Insua played Ratchaburi's last continental match despite an older injury flag. I expect Ratchaburi's block and goalkeeper to make Kobe work through several attacks for each clear chance. That's why I'm siding with Ratchaburi to keep the final margin close.
