The Mexico striker said his concentration on the club level won't waver, even with a trip to Brazil likely looming at season's end.
"The World Cup is still a way off, so I'm trying to enjoy what I'm doing right now," Peralta said at a press conference Tuesday. "The World Cup might not come, I might not even be alive then, so I play and live the next game to the maximum."
Peralta was also asked his opinion on the relaxation of Liga MX rules, starting from next season, to allow non-Mexico-born naturalized citizens to count as domestic players, regardless of how long they have been playing in Mexico's top league.
The result is likely to mean an increase of foreigners in the Liga MX over the next few years, but the 29-year-old has no problem with the changes.
"It doesn't affect us, it is beneficial," Peralta said. "They are players with very good quality that help Mexican players perform to their maximum in whichever team they are in."
Santos Laguna only managed to tie its Clausura 2014 opener 1-1 against Chivas on Friday and will play Cruz Azul on Saturday in front of an empty stadium because of a Liga MX sanction following crowd trouble last season at the Estadio Azul.
