The 26-year-old says history has proved the Bianconeri can still progress from Group B despite the draw with Copenhagen, but admits it is vital they win against the TurksJuventus defender Leonardo Bonucci believes his team's qualification to the latter stages of the Champions League could hinge on beating Galatasaray on matchday two.
The Italian champions were held to a 1-1 draw with Copenhagen in Denmark on Tuesday in their Group B opener, evoking memories of last season's surprise stalemate with Nordsjaelland.
Antonio Conte's men went on to win their group last year but, with the Bianconeri paired with Real Madrid and Galatasaray this season, Bonucci says there is less margin for error and believes victory over the Turkish giants is essential.
"I don't think we have compromised qualification," he told La Gazetta dello Sport. "The draw with Nordsjaelland last season was more serious but we still won the group.
"But we know we have to beat Galatasaray and then we can go to Madrid convinced that anything could happen.
"Real are strong, but their 6-1 win was surprising because the Turk Telecom Arena is a hot one to play in. Galatasaray are dangerous, we’ll need to be at our best."
Juventus host the Turkish champions in Turin on October 2, before travelling to the Spanish capital for a clash with Real Madrid three weeks later.
