Focused and fearless, Mexico continued to trouble Brazil in the opening stages, with Fagner in particular struggling massively to cope with the threat down his side.
Neymar broke the deadlock in the second half when he tapped in after a slick one-two with Willian carved the Mexico defence open.
Yet Silva quickly underlined the threat of the determined Mexicans, who helped eliminate defending champions Germany in the first phase.
After they conceded the goal, while they still kept on fighting, they never seemed to be in a position to equalise, even with Guillermo Ochoa denying the Brazilians a second goal until the final stages.

Japan - World Cup - 2 July 2018
Belgium 3-2 Japan with goals from Haraguchi, Inui, Vertonghen, Fellaini and Chadli. Yet another tournament at which the Red Devils flattered to deceive.
The Mexico captain, at 39 years and 139 days, had become the oldest outfield player to start a World Cup knockout match since Stanley Matthews in 1954 for England against Uruguay. The idea was to score quickly and then manage the rhythm of the game.
Brazil picked up where they had left off after the restart, Coutinho testing Ochoa with a fierce drive after cutting in from the left.
He darted across the edge of the area before a flawless backheel released Willian, whose low cross fizzed into the danger area where Neymar slid in to turn the ball home.
But Osorio turned his ire on referee Gianluca Rocchi, whom he accused of leaning towards the Brazil side in his decisions.
Neymar powered through and his low effort was diverted into the path of Firmino, who had the simple task of tapping into an empty net.
