Messi is not greater than Maradona.
I imagine these arguments have been discussed to death but firstly Messi needs to prove himself outside Spain.
To pretty much say Maradona would be just a glorified Denilson (not the lazy cunt that played for us) is stupid and quite frankly, an embarrassing comment to make. Maradona was a genius and proven in not just one league. Don't forget he was playing in the toughest league probably of all time in the 80s and was head and shoulders above everyone.
I can go on and on and on.
Go to Argentina and ask who is better, Maradona or Messi and 90% of people will say the former. By the way, there is going to be a kick ass documentary (same guy who did Senna and Amy) about Maradona coming out in a year or so about his time in Naples, especially his association with the Italian mafia, going to be very, very interesting.
Sanz, believe your old man on this one, he knows what he is talking about.
