Ronaldo is set for a rare start on the bench as Juventus host struggling Frosinone on

Friday looking to pull 14 points clear in Serie A with an eye towards next week's Champions League trip to Atletico Madrid.

Portuguese star Ronaldo brought his tally to 20 goals for Juventus in all competitions last weekend in a 3-0 win over Sassuolo.

But the 34-year-old will start on the bench for just the second time this season before the former Real Madrid player returns to the Spanish capital next week.

Paulo Dybala returns to the starting line-up, forming an attacking trident alongside Mario Mandzukic and Federico Bernardeschi.

Juventus coach Massimiliano Allegri's defensive problems have been eased with trio Andrea Barzagli, Leonardo Bonucci and Giorgio Chiellini back training.

Juventus captain Chiellini is expected to return on Friday.
