They are not even the same kind of player to begin with, Messi can create plays for himself and for his team mates, Penaldo needs to be spoonfed all the time, Messi can leave 5 guys biting the dust and Ronaldo never did something like that.
Messi is a better goaler, stats back that statement and he doesnt get 40 penals per season like the other guy.
Also judging 12 good months on one player is pretty re ed, lets judge the last 10 years...
