Mexico boss Gerardo Martino is happy hearing Manchester United are watching the young pair.
Jose Juan Macias and Sebastian Cordova have been linked with United in recent weeks.
Macias, a striker with Leon, is also interesting West Ham. Cordova is a 22-year-old winger who plays in his homeland for Club America and has been linked with United in Portuguese media reports.
Martino stated: The important teams in Europe must have in their sights on more than 100 players in the world, which does not mean that they are going to buy them. So they are in the sight of Benfica or Manchester like so many others, it's the work they must do.
If there is any comment, it's because they generate it for their performances and are doing things well, it's likely that there are scouts who take them into account."
