Video 👇 "Unstoppable" Cristiano Ronaldo will return to the Juventus team to face Ajax in the Champions League quarter-final second leg on Tuesday.

The Portuguese scored in the 1-1 draw at the Johan Cruyff Arena last week, but was one of several players rested for Saturday's 2-1 defeat at SPAL.

"Cristiano has extraordinary quality," said boss Massimiliano Allegri.

"In certain moments he becomes an unstoppable player and you can see it on his face."

Fellow forward Mario Mandzukic will miss the game with a knee injury, with Allegri saying: "He has struggled to train at 100%. These games will be better suited to players who are in their best condition, because they have to give absolutely everything."

Allegri has called on the Italian giants - who are one point away from winning an eighth consecutive Serie A title - to repeat their own heroics of the previous round against Atletico Madrid.

Ronaldo, the tournament's all-time top scorer, scored a hat-trick as they overturned a 2-0 first-leg deficit.

"It's a one-off game and we need to play with the same attitude as we did against Atletico," said the Italian.
