In soccer, they don't retire great players' numbers.
Pelé's greatness was so transcendent that since his retirement, #10 has traditionally been used by the best (offensive) player on a team, whether a club or a national team, worldwide, and that started after Pelé used the number for the Brazilian national team and his club team, Santos (and, for a couple of years in the '70s, the New York Cosmos). That was even the case when Brazil's arch-rival Argentina's third-greatest player ever (before you ask, Messi and Di Stéfano are/were the top two) got cocaine on it wore it in the 1980s.
