Why is this turning into another Ronaldo vs Messi shitefest? There's a thread already for that.
It always does. The problem with the argument stems from the fact both are in the same era.
The truth is if both had played alone in this era without the other and did what they did, there is no doubt in my mind that both would have considered the clear cut greatest of all time. However, it seems at times like the competition between them diminishes their value in some eyes.
They are both better than Pele and Maradona, they both play with attractive styles and are both very efficient and effective to their teams, more so than any players before them. Personally, I think Messi is a better player, but Ronaldo's mentality can actually give him the argument as the greater player when its all said and done.
