Blanco began in Pachuca's youth division teams and then was transferred on loan for Indios de Ciudad Juárez in the 2007 Season after having a good performance during the U-20 World Cup in Canada in 2006.
Though he did not make his debut in the Primera División with Pachuca, there were already offers for Blanco from European clubs from Spain, Greece and Holland but in the end, he settled with Cruz Azul.
[3] After Óscar Pérez's controversial signing with Tigres UANL, Cruz Azul brought Blanco, possibly, to be a substitute of Yosgart Gutiérrez, the Goalkeeper who took Perez's spot.
He played the rest of Clausura 2009 as the Cruz Azul starter goalkeeper but the team finished in the last place of the table.
