21. Frank and Ronald de Boer
Accomplishments: Ronald: 67 caps, 13 goals for Netherlands; Frank: 112 caps for Netherlands (most ever for Dutch field player)
This Dutch duo is one of the most decorated set of brothers ever to play soccer. Frank is the most capped field player in the history of Dutch soccer, having played for his country 112 times between 1990 and 2004. He will perhaps be best remembered, however, for missing two penalty kicks in the Euro 2000 semi-finals against Italy. Ronald took the field for his nation 67 times, scoring 13 goals from a host of different positions. Both have returned to the Netherlands and Ajax, the club they both played for, with Ronald serving as Frank's assistant coach. How cute.
