Inter Milan have continued their 100 per cent record under Leonardo, beating Bologna 4-1 at the San Siro as Italian football title rivals Napoli slipped up in a nil-all draw at home to Fiorentina.
After a difficult first half to the season, Inter were looking like their old selves again as they cruised to victory against their troubled opponents, leaving them perilously close to the drop zone.
Dejan Stankovic, Diego Milito and a Samuel Eto'o brace - taking his tally to 23 goals in 26 games this season - moved Inter up to fourth, for a day at least, and just eight points behind leaders Milan having played a game less.
It was a special night of celebration for Inter as captain Javier Zanetti equalled Giuseppe Bergomi's record of 519 Serie A appearances for the club.
Henry Gimenez scored Bologna's late consolation in a terrible week for the club who were hit with a three-point deduction for failing to pay taxes and player salaries.
It was vintage Inter from the off as Leonardo's team romped to their fourth straight win under the Brazilian, who took over from the sacked Rafael Benitez at the end of December.
Napoli failed to capitalise on their chance to close in on AC Milan in a dull and frustrating stalemate.
The point keeps the southerners second in Serie A, but still three points behind Milan who have a game in hand away to Lecce tomorrow.
