No way was R10 as talented as Messi. He was a showman and as wonderful as he was, he wasn't as good a dribbler, as good a finisher or a playmaker. He was a show man and did more freestyle on the pitch.
As for Maradona and Pele, it is an interesting one but time has grown their legend beyond what they exactly were. I did not watch Pele live but watched Maradona and can confidently say Messi is better. For Pele see the clips i have posted below.
Here are a couple of individual highlights from the 1970 world cup
@Andrade :
1. VS England
2. vs Italy
Looked quite ordinary (maybe even poor) in these 2 games.
