It's an argument i am bored to death of. If you ever talk about Real Madrid or Barcelona the argument always comes back to Ronaldo V Messi.It's a bloody shame that one of them has to miss out, it would be a spectacle if they'd both be there.
But if I had to choose I would pick Ronaldo to go through, it just wouldn't be the same if Ronaldo wasn't there to battle Messi and continue the infinite train of though of which is better.
I mean imagine a world cup in 86 without maradona or 50 without pele.
