Unless Ronaldo and Portugal win the World Cup, Messi is a lock for another player of the year. Ronaldo won the champions league, but Messi won la liga, golden boot,liga mvp,most assists, and top European goal scorer. Not to mention he single handedly qualified Argentina to the World Cup in the first place. One cup will never beat out getting out scored, out played, out assisted, out trophied in everything else. It's apples and oranges, but yea it's Messi.
By one cup I mean the only thing Ronaldo won this season, the champions, not the World Cup because this cup yea is like 100 ligas or 50 champions worth.
Also I don't know why some people see it difficult for Portugal to win this year, they have a strong team, one of the 2 best players in the world, and have played very well, which other top team would you pick to beat Portugal? None has looked impressive, I think it's very possible for him to win the World Cup.
