Apart from the first goal, where he was partly responsible (%25 probably), he did good. It's not easy for a GK to play at his best when all his teammates, and particularly the defense, are having a really bad day and cannot take the ball out of your own half.
He is a very good GK. A great one to have as a sub. But, he is nowhere near the quality of a Juve starter GK in the future, especially succeeding the GOAT.
