Gerardo Martino urged supporters to not get carried away after his first match in charge of Mexico resulted in an impressive 3-1 win over Chile.
Martino left MLS side Atlanta United at the end of last year after running down his contract, subsequently making a return to international football having previously coached Paraguay and Argentina.
The former Barcelona coach replaced Juan Carlos Osorio, who resigned following the World Cup in 2018 and went on to quit the Paraguay job after a matter of months in the post.
