Alvarez in for Ayala in Mexico team to face South Korea

ROSTOV-ON-DON, Russia (Reuters) - Edson Alvarez was brought in as centre back for Mexico's World Cup Group F game against South Korea on Saturday in the only change made by coach Jose Luis Osorio after the Latin Americans defeated defending champions Germany.

The 20-year-old Alvarez, one of Mexico's hottest prospects, replaces Hugo Ayala.

Mexico will qualify for the last 16 if they win and Germany fail to beat Sweden.
