"It was a difficult game, but I think we should have regrets at the three or four chances in the second half that we didn't take to win," Mancini told Sky Sport Italia after the 1-1 draw.
"In the first half Juventus had us under pressure from the start, but we improved after the break and should've made more of our opportunities.
"Games last 90 minutes. Juve could've scored another in the first half, but we had chances to win too and that's why I can't be happy with the result.
"After the break we had more control of the game and attacked their full-backs to ensure they couldn't push forward as much.
"I was satisfied when we lost at Roma, as it takes time to change the mentality and the tactics of the team. Mistakes can happen, but I think the players are improving. At the same time, when we have chances like this in Turin, a big team has to take them."
