"The difference is only seen upfront," he said of the team that has scored 25 goals in 27 games.
"We do have problems in attack at the moment, but it's not just the strikers, it's the way we all move and provide service.
"We did very well for 70 minutes, but when [Alessandro] Rosina went off and then [Eugenio] Corini, we were pinned back a bit more."
"I would like to see the free kick incident again, as Juventus are physically strong players and they tend to lean a little bit to earn fouls. Iaquinta did very well to put himself in position and lean back, forcing Colombo into the foul.
"We always struggle against players who are physically strong and can push us around."
