MILAN: Cristiano Ronaldo conceded he is not ´100 percent´ despite his goal spree for Portugal but always ready to play as injury-hit Juventus head to Atalanta on Saturday looking to extend their unbeaten run this season to stay top of Serie A.
Juventus visit fifth-placed Atalanta before hosting Atletico Madrid in the Champions League next week.
Maurizio Sarri´s side are just one point ahead of Antonio Conte´s Inter Milan after 12 matches, with Lazio and Cagliari eight points adrift of the leaders in joint third.
Atalanta have gone three league games without a win and will be eager to get back into the Champions League berths, as they sit two points off fourth place, before next week´s trip to Shakhtar Donetsk.
Atalanta´s fortunes have slipped following the thigh injury suffered to Colombian star Duvan Zapata, who scored six goals in six Serie A matches before being sidelined for their last five league games.
As Atalanta sweat on Zapata´s return, Juventus will be without full-back Alex Sandro, who picked up a thigh problem playing for Brazil, with Blaise Matuidi recovering from a rib injury.
Ronaldo had said he was not be at his best physical form, with Sarri saying the Portuguese star has a "little knee problem".
But the 34-year-old wants to make amends after storming off when he was substituted in Juventus´s last game against AC Milan.
"In the last three weeks, I have played at a slightly reduced capacity," Ronaldo conceded after his goal spree for Portugal.
"I don´t like to be replaced, no one does," added Ronaldo. "I tried to help Juve even when injured."
Full-back Danilo, who scored his first goal for Brazil during the international break, warned: "The games after the international break are never easy, let alone against Atalanta, a team who are doing well.
"We can´t make mistakes or underestimate them."
Inter will be looking to make it a perfect seven league games on the road this season as they travel to Torino, before their European trip to Slavia Prague.
Conte´s side face a tough task against the Andrea Belotti-powered Torino, who ended their six-match winless run against Brescia last time out, and are in 11th position.
Serie A runners-up Napoli are in crisis, having slipped to seventh, and desperately need a result at 14th-placed AC Milan, who are themselves floundering.
Cagliari and Lazio will look to continue their strong form at lowly Lecce and Sassuolo respectively.
Roma have a chance to move into the Champions League places as the look to bounce back from last week´s defeat to Parma at home against tailenders Brescia.
One to watch:
Carlo Ancelotti´s Serie A runners-up last season head for AC Milan amid reports he has two games left to save his job.
Napoli have gone four games without a win in Serie A to sit seventh.
The southerners have 19 points -- 13 behind leaders Juventus -- their worst tally after 12 games since the 2011-2012 season when they finished fifth.
After being held 1-1 by Salzburg in the Champions League, they travel to Liverpool next week in a key game for the former Chelsea, AC Milan and Real Madrid boss.
