Former Juventus coach Marcello Lippi has warned the Serie A champions not to underestimate Borussia Dortmund and believes that they will need luck if they are to win the Champions League this term.
The Turin outfit have one foot in the quarter-finals of European club football's elite competition after beating BVB 2-1 in the first leg at home, yet Lippi has little faith in their ability to go all the way even if they do eliminate the Bundesliga side.
