To be fair to Ronaldo and Juve, all teams need their star player to bail them out relative often. Bayern without Lewa would struggle big time, Barca without Messi and PSG without the likes of Mbappe or Neymar. I could probably find other examples.
And that's the reason they're these players. They have this extra gear and can change a game in a split second, even when they have been poor for the most of a match.
Ronaldo has been clutch as hell for a decade or more, it's numerous times he bailed Real out when they needed it the most.
I think the last decisive goal tonight was a drop from the Udinese goalkeeper, but I only seen it from one angle so far.
