Juventus coach Massimiliano Allegri has called for calm as the Serie A champions look to take another step towards a fourth consecutive title with victory over struggling Chievo on Sunday.

Juve took their lead over title challengers Roma to five points last week and with Roma away to resurgent Fiorentina, the Bianconeri have the chance to stretch their advantage to eight points.

Chievo sit just two points above the drop zone but have claimed three of their four wins this season away from home.

And Allegri, who still has doubts over Andrea Pirlo after the Italy midfielder missed training in midweek with flu-like symptoms, said he will not be taking Rolando Maran's Flying Donkeys lightly.

"It's not going to be as easy as everyone thinks," Allegri told reporters on Saturday. "Against Fiorentina, they created a few good chances with the score at 1-1 and are in god shape.

"Maran is a very good coach and Chievo are dangerous on the counter-attack."

Although midfield pair Claudio Marchisio and Paul Pogba are both one yellow card shy of an automatic one-match ban, Allegri said he could rest Pirlo until Wednesday's Italian Cup quarter-final away to Parma.

He added: "Pirlo started training again yesterday. We will see how he is today. If he's in good condition, he will play.

"Otherwise, we have Wednesday's game coming up and another next Sunday as well."

Roma coach Rudi Garcia insisted on Saturday that his side were still intent on battling for a first scudetto since 2001, telling media: "We're just about to start the second half of the season.

"There are still 57 points available to each team, so there's still everything to play for."

But while the Giallorossi are unbeaten since the start of November, they have drawn three of their past four leagues games and anything less than a win on Sunday would put Juve firmly in control.

Allegri, however, said he is taking no matches for granted.

"We're taking things one game at a time and don't want to start calculating points too much," he said.

"Obviously it's better to be eight points in front than five points behind, but what matters is being top of the table on May 31."
