(CNN) -- Inter Milan continued their march towards a fifth straight Italian Serie A title with a 2-0 victory at lowly Livorno on Sunday.
The home side had won their first two matches under new coach Serse Cosmi, but Inter did not even have to find top form to secure the three points.
The opener came just four minutes into the second half when Diego Milito twisted and turned on the edge of the box before shooting low through a crowd of legs into the corner of the net.
Brazilian full-back Maicon then sealed the victory 10 minutes from time as he burst forward unchallenged and played a one-two with Patrick Vieira before slotting home left-footed.
With only 11 matches played, Inter have already opened up a seven-point lead over second-placed Juventus after the Turin giants were beaten 3-2 at home by Napoli on Saturday.
Sampdoria also failed to keep pace with Inter as they were held to a 0-0 draw at home to newly-promoted Bari on Sunday, leaving them third on goal difference behind Juve.
It could have been worse for Sampdoria, though, as Bari's Paulo Barreto put an injury-time penalty wide, while Leonardo Bonucci then had a goal wrongly ruled out for offside.
Meanwhile, Roma ended a three-game losing streak as they came from behind to beat Bologna 2-1 in the capital.
Brazilian Adailton gave Bologna the lead on 32 minutes but Mirko Vucinic benefited from a ricochet to level three minutes later before Simone Perrotta scored the winner in the 52nd minute.
Marco Marchionni scored a brace as Fiorentina got back to winning ways after two straight defeats with a 3-1 success at home to Catania in a match that ended with 10-men apiece.
Alberto Gilardino scored the third goal for 'La Viola' while Giuseppe Mascara netted for Catania.
