Boateng: Messi and Ronaldo are from another planet

Jerome Boateng has been asked in an interview with 'Sport Bild' who will win the Ballon d'Or. The German is sure that the race will be decided between Lionel Messi and Cristiano Ronaldo.
It seems like both are from "another world" because they play very well and aren't comparable.
He told the newspaper: "It has been 10 years since Fabio Cannavaro was the last defender to win the Ballon d'Or. It is really hard as a defender. You would have to win the World Cup, make the team of the tournament and ideally score a few goals as well.
"And I am not even taking those two players from another world into account then. It will be very hard for anyone to win the Ballon d'Or so long as Messi and Ronaldo are playing at this level, regardless of whether you are a defender or an attacker. They are superstars," he explained.
He also talked about German superstars and stated: "We have some great players with the [Germany] national team like Manuel Neuer, Thomas Muller, Toni Kroos and Mesut Ozil, but nobody will get angry when I say we do not have a player like Messi or Ronaldo. They are extraordinary even at the highest level".
