City fell one point behind Manchester United in the title race on Sunday after a 1-0 defeat by Swansea.
"There were games last season where Carlos worn us on its own," said Richards. "In competitions such as those in Swansea he would get a 1-0 victory for us.
"Ultimately, it is up to the manager but I would love to see him back."
Richards added: "I've always been a big fan of Tevez-when I am asked about him I always say I love him."
Tevez, who had 44 goals in only 69 Premier League games during his first two seasons at City scored, has not played for the club since boss Roberto Mancini accused him refusing to warm up in a Champions League defeat by Bayern Munich in September.
He seemed certain to leave during the January transfer window city after his return to Argentina without permission from the club but the 28-year-old has since apologized to the club and supporters and training has resumed.
