MILAN, Nov 13 (Reuters) - Serie A strugglers Cagliari have sacked coach Marco Giampaolo, the club said on their website on Tuesday.
The Sardinians are hovering above the relegation zone but are on the same points as bottom club Empoli after winning just two games this term.
Former coach Nedo Sonetti has been linked in Italian media with a return to the hotseat.
Cagliari's match at AS Roma on Sunday was postponed after a policeman shot dead a Lazio fan and riots followed.
Siena also parted company with coach Andrea Mandorlini and brought in former manager Mario Beretta on Monday while fellow relegation candidates Livorno and Reggina have already changed coaches this season.
