Yesterday, Mexico created the sensation during its first game the 2018 World Cup in Russian Federation by defeating Germany, the reigning world champion 1 - 0.
Hirving Lozano struck the only goal of the Group F clash, but Mexico wasted numerous chances on the break to record an even larger margin of victory.
