It's a banner of the Juve-Cagliari game last may. It says: "Fumata Bianconera, Habemus scudetto" - "Black and white smoke, we have scudetto"
When a new pope is to be elected, the only way to know the results of the various votations is to look at a chimney in Piazza San Pietro. After each votation, the cardinals burn the voting papers and a colored substance in that chimney. If the smoke that comes out of it is black, it means that the votation wasn't successfull, if it's white it means that "Habemus Papam" (We have the Pope).
In this case the smoke was b/w and we have the scudetto
