Marco Di Vaio struck twice in less than a minute in the first half following two shocking defensive mistakes. Robert Acquafresca sealed the result in the 86th after another Inter lapse.

Inter was on a streak of eight successive victories which had started talk of resurrecting its title chances but has now gone six games in all competitions without a win—a run which includes five defeats.

Napoli leapfrogged Inter into fifth after two Edinson Cavani goals helped it win 3-0 at Fiorentina. Bologna extended the gap on the relegation zone to seven points.
