Inter legend Materazzi: I had to cut up socks of Man City's Balotelli
The Manchester City striker is a huge Milan fan, but made his name at Inter.
"Mario wore Milan socks to training once at the Pinetina ground. At that point, I cut them up, as those colours look terrible on him," smiled Matrix.
"He understood the lesson. In any case, Balo is truly a good kid and I hope he can win at Euro 2012. It's tough to find players so young who have already won so much."
