Put it this way. He isn't getting blamed but he didn't do what his rival has been doing again and again and again for the last 3-4 years.
Scoring goals? It's his goals in the previous round that got them here.
The same argument can be said that Barca as a team aren't doing what their rivals have been doing again and again and again.
Could any of the Ronaldo stans honestly say that they could see RM throwing away a 3 goal lead?
If you'd asked me before tonight which team of the two would be most likely to do that I would've said Barca and it isn't even close. Everyone would have.
