Juventus, chasing a fifth successive title, have recovered from a slow start and bounded up the table as close-season signings Mario Mandzukic and Paulo Dybala have found their feet after initially taking their time to settle.

He also saw no reason why striker Simone Zaza should leave the club despite making only seven league appearances, and scoring two goals, this season.
"I don't understand why he should go away, there should not be this storm about him," he said.

"We have four top-quality players in attack and they should fight for their places."
Allegri then used a cycling comparison to describe the rest of the season.

"We are like a cyclist who is racing against the clock, where strength is not enough but a good mental condition and concentration are also needed."
