A third straight win in Serie A - and fourth in all competitions since Leonardo took charge during the winter break - lifted Inter to fourth place in the table, eight points behind leaders AC Milan but with a game in hand in their favour.

Dejan Stankovic put Inter ahead after 20 minutes and Diego Milito added a second nine minutes later.

Cameroonian striker Eto'o made it 3-0 after 62 minutes and grabbed the fourth goal nine minutes later, rendering Henry Gimenez's effort for Bologna in the 76th minute of no great concern to the hosts.

Second-placed Napoli, who have played two more games than Inter, who they head by five points, were held to a goalless draw at home by mid-table Fiorentina.
