Mexico has won four straight qualifiers over El Salvador. El Tri plays Honduras at San Pedro Sula on Tuesday in its next qualifier.

Osorio was hired last month to replace Miguel Herrera, who was fired after punching a reporter on the day after Mexico won the CONCACAF Gold Cup. Osorio started Moises Munoz in goal over Guillermo Ochoa, moved defender Miguel Layun from left to right back and started Hugo Ayala instead of Diego Reyes, considered a popular option to replace the injured Rafael Marquez.
