At this point a draw wouldn't be too bad for them. It all really depends on CR's form imo, he certainly wasn't 100% before the world cup since his pysio advised him to skip to avoid aggravating already existing injuries.

That's Ronaldo for you, pysically incable of being injured has carried some sort of injury at all times during the majority of his career, and is still one of the best player on the planet and potentially of all time.
