Torino coach Sinisa Mihajlovic admits Joe Hart must do better after an eventful debut.
The on-loan Manchester City goalkeeper conceded two goals in the 2-2 draw, being directly responsible for one of Atalanta's efforts.
"As I said, I never get angry at my players for a wrong pass, a missed penalty," Mihajlovic told reporters. “I get angry when they don't play how we prepared during the week."
"Hart saved us on one occasion, but of course he could have done better on the corner. But it happens.
"We've lost due to individual mistakes. This is positive in a way because it's easier to sort out individual mistakes than those made by the whole team."
