Ventura's men produced a solid performance to win 2-0 at Sassuolo last weekend. The result was Torino's fourth victory in their last six league games and lifted them to seventh in the standings.
They are now only three points behind Inter Milan, who occupy the last Europa League qualifying spot.
"We are on the right path," Ventura said. "I'm very pleased with my team's performances but we cannot relax.
"There are still many games left to play and things can turn around when you least expect it.
"That is why we have to remain humble and focused."
Atalanta travel to Turin on the back of two straight victories but having mustered just one win on the road this season, a 1-0 triumph at Chievo on October 5.
Last weekend's 1-0 victory over Cagliari allowed Atalanta to move seven points clear of the drop zone and marked the fourth time this season where the Bergamaschi managed to keep a clean sheet.
"Our victory against Cagliari was important," Atalanta coach Stefano Colantuono said. "We handed a good performance and beat a worthy rival.
"We are doing well in recent weeks but we must keep our concentration high and continue to climb up in the standings."
Atalanta are optimistic they can do well in Turin.
"The important thing for us was to have won a second consecutive game," said Atalanta midfielder Cristian Raimondi. "That allows us to prepare for our game at Torino with more calmness.
"We know we face an important test in order to finally find some continuity but I'm confident we can succeed."
The visitors must overcome the absence of defender Stefano Lucchini and midfielder Giulio Migliaccio, who are both suspended.
