Andrea Pirlo has warned his Juventus teammates that Borussia Dortmund remain a team to be feared ahead of next week's Champions League clash.
The Italian champions welcome their German counterparts to Turin on Tuesday in the first leg of their last-16 tie.
Dortmund had sat at the foot of the Bundesliga table at the beginning of February, but three successive victories have since reinvigorated their domestic campaign.
Jurgen Klopp's side have had no such problems in Europe, however, and Pirlo says that Juve cannot afford to take them lightly.
"Borussia Dortmund are a side to be feared, as we see what they've done in the Champions League," he told Sky Sport Italia.
"The first leg will be fundamental and we must try to win without conceding a goal."
Massimiliano Allegri's side travel to Signal Iduna Park for the return leg on March 18.
