Juventus underlined their status as Serie A champions in-waiting once again at the weekend after taking their lead over stuttering title challengers Roma to nine points.

But while Chiellini warned of the threat posed by the Germans, he believes Juventus' ambition to make the final stages of the competition will come to the fore.

"Dortmund have some good players, a few who played well at the start of the season are coming back from injury, but over two legs anything can happen," Chiellini said to Rai television.

"We can't afford to gift them opportunities to launch counter-attacks, because they have players who excel when you give them space - although that tactic can be very risky. We have a lot of respect (for them) but we really want to win this game, progress and keep our European dream alive."
