The Argentina international spoke to the family of 18-year-old Kieran Crump Raiswell, who was stabbed to death in Whalley Range last week, when they were invited as special guests to Saturday's 2-0 win over Fulham.
"I would like to ask anyone who may be able to help police catch who is responsible to come forward," The Sun quotes Tevez as saying. "Kieran's family deserve answers."
A 26-year-old man has been arrested on suspicion of murder.
