The record champions at a 13 000-seat ground
Al Shabab Stadium is the smallest of the eight venues in use, and this is the match the schedule has put there: Thailand against the team with more Asian Cup titles than any other. Japan have four. Nobody else in Saudi Arabia has more than three.
Small grounds have a way of changing the texture of a fixture like this. Japan have not won the tournament since 2011, which for the record champions is a longer gap than the one that separated their first title from their third.
Thailand come in with a third place from 1972 and seven appearances since that produced nothing comparable. A result here would be the biggest single thing they have taken from an Asian Cup in half a century.
