Juventus coach Max Allegri concedes tonight's clash with Maccabi Haifa is a must-win game.

Allegri says he's never suffered such a poor start to a season over his career.

He stated: "We have zero points after two games, it means having to win. But we don't have to be in a hurry or anxious, we don't have to overdo it like with Bologna. Champions you have to start from a victory. In these moments, hurry and anxiety lead you to make mistakes.

"My teams have never started so badly but in the first year we took a risk at home against Olympiakos. As long as mathematics does not condemn us, we will have to put in a brick."

He continued: "In football you never know, we work on ourselves. If we don't beat Maccabi, we don't need to. Then we have the championship, now one thing at a time. One thing is the same for everyone.

"I don't know if it will be the most important, maybe it will be in a month or six months ... Tomorrow it is because it is the closest."
