Two of Serie A's Sunday games have been called off by officials because of deteriorating weather conditions in Italy.

AC Milan go top; Cagliari climb

Juventus's match at Bologna and Fiorentina's trip to Parma have both been postponed.

AFP reports that the decision in Bologna was taken by the local police after talks with security officials and both clubs.

"After verifying the structure and installations [at the ground] and bearing in mind the weather forecast and the huge amount of snow on the stands, it was decided that the game could not go ahead with the necessary safety conditions," Bologna's chief constable Vincenzo Stingone told AFP.

The news will come as a blow to Juve who could have returned to the top of the Serie A summit with an away win against Bologna. Instead the Turin outfit could only watch as defending champions AC Milan went top with a 2-1 away success at Udinese.

Milan are two points above Juve but Antonio Conte's side still have two games in hand.
