Ronaldo, meanwhile, was absent from a number of games at the start of the season after damaging his adductor, and missed the annual FIFA best awards ceremony after nursing the minor injury.
“Cristiano has a little fatigue to the adductors. I don’t want to take any risk.” Juventus manager Maurizio Sarri said ahead of the tie.
For his incredibly high standards, Ronaldo made a relatively slow start to his second season in Italy, scoring against Napoli and Hellas Verona in his first five games played.
But he certainly made up for it in the following months.
Messi missed Barcelona’s opening four games of the season because of a foot injury sustained while playing for Argentina in this summer’s Copa America.
And he admitted at the start of the season that he is a long way from his best, admitting to being “tired” and “sluggish” after returning from his summer break.
