Atalanta, who exited the Champions League and Coppa Italia last month, are struggling to regain momentum in the title race and have been winless at home in the league since the end of December.
Despite winning just three of their last 10 Serie A games, they remain third on 55 points, one point behind second-placed Napoli and two off Inter before those sides meet at the Diego Armando Maradona Stadium later on Saturday.
Venezia extended their winless run to 10 games as they sit 19th with 18 points.
Atalanta renewed their hopes of first top-flight title when they cruised to a 5-0 win at lowly Empoli last Sunday but looked slow and predictable against a promoted Venezia side.
