Hard to compare Messi with Pele, Maradona etc as players are fitter now & defenders aren't allowed to tackle. It's difficult to know how some of the modern players would get on when subject to 15 challenges which would now be a red card. Pele was a lazy twat though for sure.
Speaking of lzy twats; imo Ronaldinho at his peak for Barca was as good as anything I've seen so far as purely attacking goes. He combined the short passing/dribbling game with long passes & incredible shooting/free kicks/crosses. I enjoyed watching him even more than I do Messi. What a pity he couldn't be arsed keeping it going.
