River Plate flies into Seattle for their first ever Club World Cup appearance, taking on Japan's Urawa Red Diamonds in the opening game. The Argentine side has added only one senior recruit and a handful of youth prospects, so the focus stays on integration and chemistry. Training will be at the Seattle Sounders' elite centre, with media allowed inside. Urawa arrives in patchy form but boasts a potent attack led by Ryoma Watanabe. The group also pits River against Monterrey and Inter Milan, turning the Pacific coast into a battlefield.
