The Sunday Mirror says Tevez made the confession in an interview with Susana Gimenez.
He remarked: "I don't have any new friends in Manchester. I am always with my family and lifelong friends. I don't even leave my house. I'm the stay-at-home type.
"When I have my dad and friends over we have a barbecue, we have fun. But I'm always on my own, especially in the last few months. I was with friends, but I've found the past few months very hard."
