Materazzi swapped shirts with the AC Milan striker in the derby clash last night, that Inter won 2-1.
Materazzi said this morning: “I exchanged shirts with Ronaldo at the end of the game. On the field I do not have friends, for me he was a traitor. We give everything on the field, isn’t that what football is all about?
“But we shared many things when he was with Inter and our friendship remains.”
