"Diamanti was our best player, but life goes on," Cristaldo told Corriere dello Sport after scoring twice to help his side to a 2-1 victory over Torino.
"Davide Ballardini has put his faith in me and after the game he shook my hand and congratulated me.
"I'm pleased with my goals but this is the team's victory. I am happy, this is a very important win.
"I have finally got the chance to play in my favourite position, playing alongside a strike partner who is a point of reference for me up front."
