Juventus coach Massimiliano Allegri insists his side will need to again subdue Borussia Dortmund's attack on Wednesday to reach the Champions League's quarter-finals despite holding a 2-1 first-leg lead.

Hosts Borussia will be bidding for their first win over Juventus in Dortmund at the fourth attempt after Marco Reus' goal in Turin last month was cancelled out by first-half strikes from Carlos Tevez and Alvaro Morata.

The 47-year-old Allegri says his side's hopes of reaching the quarter-finals hinge on containing Reus and Pierre-Emerick Aubameyang who have been in rich goal-scoring form in recent weeks.

"It will be a great game and I honestly can't see it ending 0-0. I think we'll need to score at least once to go through," said Allegri, who will be without injured playmaker Andrea Pirlo.

"In the first leg we didn't allow them a shot on goal, Dortmund only scored from our mistake.

"Dortmund have plenty of pace in their ranks. We must put in a good technical performance and strike their weak areas."

Allegri admits he is pondering a possible 4-3-1-2 line-up or a 3-5-2 formation which would see Patrice Evra, Paul Pogba, Claudio Marchisio, Arturo Vidal and Stephan Lichtsteiner crowd the midfield.

Juventus received a boost on Saturday when defender Andrea Barzagli made his first start, in the league win against Palermo, after a long injury lay-off.

"I still have some doubts over the starting team and need to decide whether we play three or four at the back," said Allegri.

Juve's veteran goalkeeper Gianluigi Buffon says he is relishing the chance to play at Dortmund's 80,000-capacity Westfalenstadion stadium.

"The fans here? It's fervent from start to finish. It can be a real boost for the hosts but can also motivate the visitors," said the 37-year-old.

"It's always a pleasure to come back to the Westfalenstadion. Matches here are never trivial."
