Too bad for Ronaldo, he was unable to continue the game after getting injured, I just hope it's nothing much, And he'd be back for Juventus Champions league tie.
I wouldn’t worry too much about Ronaldo, he’s a machine. He very rarely misses many games through injury. His injury record is good.
Hopefully, Ronaldo will come back immediately. He has a long way in the Champions League with Juventus and he should definitely not miss it.
I think he has the best physios in his team this is why he don't have many injuries in his career even if he plays so much time in a season.
