No wonder, then, that a nation breathed a collective sign of relief when Blanco reversed his decision to quit the Mexico team after scoring twice in the decisive 3-0 triumph over Honduras which booked their place at the World Cup finals.
The spat which prompted the resignation threat had been typical Blanco.
He was fuming because the Mexican federation (FMF) flew him in for the vital clash from Spain, where he plays for Real Valladolid, on a flight which he considered to have too many stop-offs.
Federation officials had also controversially refused to pay for an injury operation, and Blanco, who has never cared who he upset, simply was not having it.
Changing his mind, however, is also a Blanco prerogative, and this he duly did, when his notoriously fiery temper cooled.
"I'll be here if Aguirre needs me," he then pledged.
For Mexico, a team without Blanco is like rice without beans.
The 29-year-old was named after the legendary Aztec warrior emperor Cuauhtemoc, a national symbol whose statue keeps guard over Mexico City's 8.6 million inhabitants.
When he scores, Blanco sometimes salutes his illustrious ancestor by bending down on one knee and extending his right arm to the heavens.
