He'll win the Ballon d'or IMO. 2/3 voters are the national team coaches and captains, I'm sure most of them will vote for Leo. However, the journalists almost always vote for the one who's won most trophies so I think Ronaldo will get most of there votes. It'll definitely be interesting though, I bet a lot of people are gonna cry conspiracy if he wins it this year.
But, even then I wouldn't be surprised. It took him injured, Ronaldo crying, a reopening of the voting just so Ronaldo could win and he won by 3%. All the other years Messi had like +20% lead, other then 2010. But if he carries on his good form, he'll definitely win.
As for La Decima, the CL is almost always forgotten when it comes to World Cup years. More people are going to remember Ronaldo missing chance after chance with Portugal and failing to get out of the group stage, rather than him scoring 17 CL goals.
