For me it's a shame he didn't come along 10 years later when the TV cameras would have been there to capture it all so I could see it.
I have to take others words over just how good he was but by the sound of it despite being off his tits a lot of the time he was still running rings around everyone at a time when the opponent was allowed to butcher you from behind and pitches weren't carpets.
From the stuff I've seen of him you could tell he was a cut above similar to what I watch Messi the ability to play the game at 100mph but make it look like slow motion is a unique skill very few possess. The ability to think as fast as he did and then execute the skills to move away from players was unreal.
He also has the fairy tail story with Napoli helping them to that title makes him a legend in Naples.
For those in their 40/50's who grew up watching Maradona he's probably what people in their 20/30's think of Messi it's like they're cheating it's not actually possible to be as good as they are/were at football.
