I'm too young to ever see Maradona play, but from the clips I've seen of him, Messi looks the much better player IMO.
I just think that of the clips of Maradona that is always on TV, the defending just looks very bad, whereas with Messi, he easily goes past defences where the defence has done nothing wrong, it's just his brilliance.
My opinion probably doesn't count for much though seen as I've never saw Maradona play.
And I agree with the Spurs fan about Pele. I reckon he was probably the equivalent of Jermaine Defoe or Darren Bent of the 60s, 70s. Just a poacher, nothing much else about him.
