yes but maradona not only carried a team (napoli), but he carried a country in the '86 world cup.
the maradona and pele eras were fucking brutal too, when compared to todays. christ, they've almost removed tackling from the game today
yes he did carry club and country
Yes there is more protection from refs
But,
The game is much faster, defenders and full backs are better, the holding defensive mid position did not really exist then as it does now
Maradonna innovated a lot, and did what was then unseen and seemed impossible, but the talent pool has grown the game has evolved, lots of talent out there
Add in fixture congestion with club leagues, cups, european games, internationals and friendlies...
Maradonna was hanging by a thread towards the end, loaded up with cortisone and other drugs to get through games, plus ped's , and his rec habits
The modern game has changed, real athletes nowadays, lamps, cristiano, ibra, kaka, nani...
