Scoring a lot of goals in the CL means nothing since the majority of games a player will play is against crappy minnows from countries like Cyprus, Latvia, and Finland.
Besides, you conveniently forgot to mention the time Ronaldo was part of that Portugal team that was humiliated before the whole world when they lost to Greece (!) at the euro final before a home crowd. Messi and Argentina never would have suffered such an indignity.
And no Ronaldo didn't drag Portugal to the World Cup alone. They've made it plenty of times to the World Cup without him. And at the World Cup tournament itself, he's hasn't done anything significant. In fact, Portugal's best ever placing at a World Cup occurred
without him.
Some of you guys in love with Ronaldo seem to have a lot of misinformation.
Here's a website called Messi vs Cristiano Ronaldo which is devoted to comparing the two:

as you can see, Messi comes out on top.
