Didier Deschamps might achieve the feat of winning FIFA World Cup both as captain (1998) and manager (2018) for France.
I know Franz Beckenbauer had already done it before. Is there any other person to achieve that?
There are 3 footballers who won the World Cup both as a player and as a coach:
Mário Zagallo, Brazil (1958 & 1962 as player, 1970 as coach)
Franz Beckenbauer, West Germany (1974 as player, 1990 as coach)
Didier Deschamps, France (1998 as player, 2018 as coach)
Out of them only Beckenbauer and Deschamps were the captains of the winning squad.
