League: Serie A (Italy)
When: 1989/90 season
Players: Diego Maradona, Andrea Carnevale and a young Gianfranco Zola
Maradona scored 16 league goals as Napoli won a second title in four seasons in what was a golden period for the club. A year earlier they won the UEFA Cup and in the '87 title-winning season they picked up the Coppa Italia, too.
And Maradona, who was not known to live the most professional lifestyle, wearing a kit sponsored by Mars is pretty funny.
