Milan and Juventus both suffered European hangovers, with leaders Juve being held at Treviso and the Rossoneri losing to Lecce.
Lecce are struggling in the relegation zone, but boosted their faint hopes of surviving the drop with a fine 1-0 victory over Milan.
Klas Ingesson scored the winner after 53 minutes, to further damage Milan's chances of overhauling Juve.
Fabio Capello's men, fresh from their 2-0 defeat to Arsenal in the UEFA Champions League, again failed to find any fluency and were held to a disappointing 0-0 draw at Treviso, the league's bottom club who had picked up only two points in their previous nine games.
In the day's final game there were no such surprises, as Internazionale overcame Messina 3-0 in another clash between a team in the top three and a team in the bottom three.
Santiago Soliari (15 and 26) and Obafemi Martins (19) put Inter three up within the first half an hour, but surprisingly they never extended their lead as Messina fought to the death.
