Ronaldo didn't win anything in 2013 and won a Ballon D'Or for nothing just because Messi didn't have a year as good as the previous and he was injured too, but that's not the point anyway because even if you don't win it's not up to you, he wasn't even close to winning a major and he wasn't playing for underdogs to say any trophy would be gold.
2013 should've went to Robbery, 2014 was between Messi's World Cup run, Neuer excellent parades and eventually someone else from Madrid but not Christina and I would've included Arda or Koke at least as honorable mention.
2015 clearly Messi, 2016 between 1.Griezmann, 2.Messi and 3.Suarez if it would be a fair vote.
But the old Ballon D'Or made some crap choices too based on some very demoted criteria.
They should instruct the voters more, now you can vote Juan Cuadrado as best player and he gets the points just because you're Colombian and you want him to get the points.
