Mexico head coach Miguel Herrera will have some work to do after watching his team get dominated by World Cup-bound Bosnia-Herzegovina in Chicago.
With only one friendly to go before heading to Brazil, El Tri was outplayed from the opening kick and failed to capitalize on the few opportunities the team had in the disappointing showing.
Izet Hajrovic scored the winner for Bosnia-Herzegovina in a first half.
Herrera experimented with a new starting lineup in Chicago, with Javier 'Chicharito' Hernandez earning his first start since the end of the Premier League season. He also gave Alfredo Talavera the nod at goalkeeper ahead of Guillermo Ochoa and the injured Jesus Corona .
Herrera hopes to have his World Cup XI set before Friday's friendly against Cristiano Ronaldo and Portugal in Foxborough, Massachusetts. He will likely announce the lineup he will use when El Tri takes on Cameroon in their World Cup opener at a press conference on Thursday.
Herrera voiced his displeasure with the fact that Bosnia head coach Safet Susic handed in his lineup prior to the match before changing it up prior to kickoff. But El Tri's issues went way beyond what some may consider poor sportsmanship from the European nation.
Bosnia-Herzegovina opened the match on fire, with Manchester City star Edin Dzeko getting off three shots in the opening seven minutes. The team finished with eight shots in the first half, while Mexico had three.
Chicharito gave El Tri its best chance of the night in the 24th minute when the Manchester United striker brought down a fabulous long ball from Miguel Layun with an exquisite first touch, but his shot powered off the post and wide.
The missed chance would be a huge blow for the home side, which conceded a goal less than 20 minutes later. Sejad Salihovic found Hajrovic at the six-yard box with a perfectly placed pass and the Galatasaray man was able to fire it past Talavera.
Herrera went to his bench early in the second half and the hosts showed some life, but failed to really test Bosnia-Herzegovina's back line, with the exception of Maza Rodríguez and Miguel Ponce forcing goalkeeper Asmir Begovic into two diving saves in the closing minutes.
Mexico's eight-game unbeaten streak ended with the team being dominated on shots (13-9) and possession (61-39 percent).
