Serie A leaders Inter Milan failed to capitalise on the draw between closest rivals AC Milan and AS Roma when they were held nil-all by Genoa at the San Siro.
Inter have 59 points from 27 games after their fourth draw in five league games and maintain the four-point lead they started the weekend with over Milan, who failed to turn dominance into goals in another goalless draw in Rome.
AS Roma are three points further back in third.
Palermo regained fourth place when Fabrizio Miccoli's late goal gave them a 1-nil home win over relegation-threatened Livorno.
Palermo have 46 points from 27 games, two more than Juventus who won 2-1 at Fiorentina.
Sampdoria are also in the chase for Champions League qualification after a 2-1 comeback win at home over Lazio that puts them one point behind Juve in sixth.
