Juventus midfielder Andrea Pirlo has predicted a tough battle with Siena when they clash in Serie A on Sunday.
The Turin giants are a point ahead of Scudetto holders AC Milan going into the fixture, but the Italy international said that recording a victory will not be a formality.
"It will be a tough game against an organised team that plays good football, so it will be hard, as all the matches are," he told the Juventus Channel.
Pirlo was also full of praise for coach Antonio Conte, with the team looking to secure their first Italian top-flight title since 2003.
"Conte is a very good coach who can give so much to the team," Pirlo said.
"We are first in the standings and we hope to stay like this."
Juventus are unbeaten in 20 league games this season, whilst Siena are in need of points as they sit precariously above the relegation zone in 17th position.
