How does a team go into a final when its opponent beat it 6-1 the first time they met? That was the challenge facing Mexico as it prepared to face Nigeria in Friday’s final of the Under-17 Wold Cup inAbu Dhabi. But Mexico’s captain, Ulises Rivas, says his team will be ready. “It’s a World Cup final and this is a stage where you have to be at yourbest,” he said. “Obviously, we started badly, so there was nowhere to go but up for us. The last games were difficult ones, but they’ve made us stronger and more together in the teamand they’ve prepared us for the final.” Rivas said that team unity and an ability to move the ball around were Mexico’s strengths.
