Two late goals from Francesco Totti gave Roma a nervy 2-1 win at home to Cagliari on Sunday and ensured the Serie A title will be decided on the final day of the season.
Inter Milan maintained their two-point lead at the top with a 4-3 success over Chievo at the San Siro that proved less comfortable.
Inter travel to Siena while Roma will be entertained by Chievo next weekend where the nerazzurri can sew up a fifth title in a row with victory while Roma need to win and Inter to fail to do so to secure their first scudetto since 2001.
At one stage in the day, Inter were cruising at 4-1 while an Andrea Lazzari goal direct from a free-kick gave Cagliari a
shock 1-0 lead in Rome with just 17 minutes remaining, meaning Inter were virtual champions.
Inter fans were celebrating in the stands but two goals just four minutes apart from Roma captain and talisman Totti silenced them.
And it was the perfect response from the 33-year-old forward who was roundly criticised in midweek after being sent off in Roma’s 1-0 Coppa Italia final defeat to Inter for a wild kick at Mario Balotelli.
