Allegri wants 'aggressive' Juventus against Barca
Massimiliano Allegri believes Juventus must be positive at Camp Nou when it begins its UEFA Champions League campaign against familiar foe Barcelona.
The Italian champion knocked out its Spanish host at the quarter-final stage last season on its way to the final, where it lost 4-1 to Real Madrid in Cardiff.
Juventus kept back-to-back clean sheets against Luis Enrique's side in the last-eight tie, yet Allegri feels his team will need to score to get something out of their Group D opener on Wednesday (AEST).
"We're not yet in peak condition. The aim, as always, is to be fighting on all fronts come March," he said. "Tomorrow we need to score, as to keep a third consecutive clean sheet against Barcelona would be tough.
"We need to play with great enthusiasm and passion as we bid to reach the knockout rounds."
Barcelona have topped their group in each Champions League campaign since the 2007-08 season.
However, this season's Barca is a different proposition to the one Juventus faced in April; Ernesto Valverde has taken over from the departed Luis Enrique, while Neymar joined Paris Saint-Germain.
New signings Ousmane Dembele - drafted in to help fill sizeable the void left by the Brazilian's departure - Paulinho and Nelson Semedo could all feature for the first time for Barca in Europe.
"It is actually strange to see Barcelona with three new players," Allegri said. "They lost Neymar and replaced him with a young man like Dembele, but still today, along with Real, Barcelona are one of the two strongest teams in the world.
"Juventus have changed a lot - and have changed well - and that is a long story about the good work done by the club. Both clubs have moved very well."
