100%. That Argentina 86 side was average at best, but the inclusion of Maradona alone made them the best team in the world and worthy winners. When Pele played for Brazil he was surrounded by 6 or 7 world class players, particularly in 1970.
Quite right. As Jimmy Greaves said, people can name most of the 1970 Brazil team, quite a few of the 1978 Argentina team but struggle to name any of the more recent team of 1986 other than Maradona. Napoli had won nothing in their history until Maradona arrived. Two league titles, an Italian Cup, Cup Winners Cup and a Super Cup during his time there and nothing since he left. Far more influential than just about any other player. And, unlike Pele, he did it in Europe in a tough league. He was kicked from pillar to post without the protection that Ronaldo and Messi get, playing on far worse pitches.
Whether to like him or not is irrelevant. To deny he is one of the, if not the, greatest players of all time suggests a lack of knowledge about football.
