Marcello Lippi has warned Juventus they don't have the title wrapped up when the season resumes.
Juve lead the table by a point ahead of Lazio.
“He has the play, alright," Lippi said of Juve coach Maurizio Sarri to Tuttosport. “When the season stopped, the learning period was about to end.
“In the last match against Inter I saw a tactical organisation that will be useful for the second half. Sarri will be able to start from there."
But he added: “Lazio are not to be underestimated, though.
“They play very well and are charged by what they've done up until the stop.
“They have escaped the danger of having to cancel the championship. In addition, they have the leading goalscorer. It will be a great battle."
