Diego Maradona
In March 1991, Maradona failed a drug test for cocaine. He was given a 15-month ban and a fine, so he missed the rest of the 1990-91 season and the entire 1991-92 season. After being allowed to return to football in June 1992, he didn't want to return to Napoli, and he asked for a transfer. He eventually signed for Spanish club Sevilla. He stayed there for one year. He moved back to the Argentine League with Newell's Old Boys in 1993, and stayed there for one season. Maradona ended his career by making a return to Boca Juniors in 1995. He stayed there for two years until retiring on 25 October 1997. He played his last match against Boca's rival River Plate, and Boca won 2-1.
