And he looked ahead to the visit of the Scottish champions with a warning.
He said: "Celtic are a very physical team, who will want to make things difficult for us.
"We have full focus on them and only after the game will we think about our next two Serie A games against Verona and Monza.
"I am very happy with the way we are playing just now. We are on a good run. It's never easy to come here to Venezia and win."
