The Rossoblu have a win against AC Milan and a defeat against Atalanta so far this season.
“We were not phenomenons when we defeated Milan and we are not poor following Sunday’s defeat,” said Zenoni.
“The Milan game was something different, whereas the Atalanta match was surely easier on paper, but the pitch has proven the contrary.
“We’re still in the second matchday and we have margins of improvement. By training well we have all the time to recover.
“Looking at the teams in Serie A, I think that Bologna are fine as I don’t see what we have less than other teams. There is a well-equipped defence that has conceded more goals than us, for example Milan.”
