Boca recently lost 2-0 to derby rivals River Plate, which led to coach Carlos Bianchi quitting, and they have struggled in the Apertura Championship and Tevez is keen to help.
"Every Sunday in Manchester I have the chance to watch the games that Boca play," Tevez told Argentinean media.
"I would like to return one day to help them get out of the difficult moment that they are in. It is not common that Boca lose so frequently in the derby match against River.
"I am a Boca fan and would like to be there but that can only be possible in a few years, not now.
"I would like to return to Boca in four or five years time when I am still fit to play. I wouldn't want to return to Boca being fat and without any chance of playing correctly.
"At the moment my life and my career are focused on Manchester United, but I always know everything that happens with Boca."
