For 55 minutes, Mexico were downright poor. They struggled to create anything as they consistently misplaced passes, and they made a huge mess of every single opportunity that they got. It was actually an embarrassing performance. Then, Efrain Juarez scored a lucky goal and the flood gates opened. Now, El Salvador are down 3-0, taking the beating that many predicted before the start of the match.
The first goal was assisted by Giovani dos Santos, who put in a low cross from the right side of the box. Juarez had his initial shot saved, but he fell on the rebound, somehow pushing it into the back of the net with his head unintentionally. It wasn't a pretty goal, but it gave Mexico the confidence they needed.
Aldo de Nigris came into the game for Israel Castro, who was awful, to be honest, and he made an instant impact, scoring a goal after splitting three defenders.
The final goal was scored by Javier Hernandez, who headed in a bit of an odd, scrambling attempt. Mexico are very much in control now and will probably not stop at three goals.
