Marchisio hails powerful Juventus performance at Celtic
"It is a very important victory, especially as we can be a little more concentrated on Serie A. We haven't passed through yet, but it is a great win in a difficult arena and we put in a fine performance.
"It's true it is tough to overturn a 3-0 away win, but we must never be certain and always go out there with the same determination.
"This team is having a great Champions League. This was an important signal to ourselves and nobody else. It was crucial to come here and score a goal, but we ended up getting three."
