Juventus assistant manager Marco Landucci applauded his players' attitude and believes they are building consistency following their Coppa Italia victory over Sampdoria.

The Bianconeri made a strong start to their title defence with a commanding 4-1 win over the Blucerchiata at the Allianz Stadium.

Goals from Juan Cuadrado and Daniele Rugani put the hosts in control and despite Andrea Conti's reply for the visitors, further strikes from Paulo Dybala and Alvaro Morata sealed the passage into the quarter-finals.

Landucci oversaw Juve's fortunes in the absence of Massimiliano Allegri, who is serving a touchline ban in the Coppa Italia held over from his first stint in charge of the club.

And the assistant hailed the efforts of his squad, who are now unbeaten after 90 minutes in their last 11 across all competitions.

"We put in a good performance, which wasn’t easy with so few people in the stadium," he told Sport Mediaset.

"We had the right attitude, were fired up, and it was very important that we go through to the next round, as the Coppa Italia is a great tournament. Everyone did very well.

"The attitude is crucial, and we had many games with the right attitude, even missing key players. There are no easy games; we saw that [when] we lost more points against the so-called smaller sides like Verona, Empoli and Udinese.

"The only thing that matters is hard work, attitude and desire. We are finding some consistency now; we need to speak with actions rather than words."
