No. Back to what zzwampfen had said, Ronaldo and Zidane were the pinnacle of my generation, and they still haven't been recognized by the world as a whole to be better than Pele/Maradona.
Ronaldo will probably never be as good as Eusebio, unless he brings the small country of Portugal glory in the future (near future in Euro 200

, and I doubt Messi will ever touch what Diego Maradonna did with club (Napoli) and country.
Forget potential at this point, Ronaldo and Messi aren't even close to being the best of this generation, yet best 'ever'. But Ronaldo is getting better every year, and Messi is...well he can almost play a full season, so that's porgression I guess
