Ah the Ronaldo v Messi debate.
Such a difficult call isn't it to put one above the other. I guess in some ways it's in the eye of the beholder. Messi can do amazing things that Ronaldo would not quite match and vice versa with Ronaldo over Messi.
Also, I suppose there is the unconcious bias towards whether one prefers Real or Barcelona.
I veer to the Real side, however I would have to put both players joint top. Cannot split them at all.
If push came to shove however, and I had a gun pointed to my head for an answer, Ronaldo has won multiple titles in three major European leagues.
