Leo Messi's pure technical skills can't be compared to anybody, period. Not in the Barça team nor in any other team in the World there is another player on his level, the closest one to him is Iniesta at the top of his game, with the difference that the goals scored by Andres in his whole career get scored by Messi in just one season.
They keep on comparing Messi to Maradona but, to me, the comparison which fits him the most is the one with Platini. Indeed, to me Messi is the Platini of our days: both of them have the incredible vision of the best #10 while at the same time also being the best scorers of their era; both of them possess amazing class and dribbling and can build up the action from their own midfield and then finish it themselves with a goal.
It's not a matter of being Barça fan or not, it's just evident to everydoby who really understands even a little bit of football that nobody, nowadays, can stand up to Messi when he is at the top of his shape.
