The defending champions have started their campaign with three consecutive wins, while newly-promoted Cesena have taken four points from a possible nine.
Despite Juve being expected to earn a win on home turf tomorrow night, Allegri believes that his team will be given a stern challenge by the visitors.
"Cesena have shown good form so far. They are an aggressive side that doesn't give away much space," he is quoted as saying by Sky Sports News.
"This is a difficult match, but in order to win the league title it's important to win against the smaller clubs. We need to arrive at the big games in a strong position."
Juventus head into tomorrow's match on the back of a 1-0 win over Allegri's former club AC Milan in the league.
