Hugo Lloris - France
The Goalkeeper has close to 100 caps for the national team, and is their most experienced player. It is no surprise that the Tottenham captain has been chosen to lead the team in the WC as well, he has been the first choice captain since 2012.

Mile Jedinak - Australia
With the most caps (76) after veteran Tim Cahill (106), Mile Jedinak has been chosen to lead the Socceroos in Russia and has served as their captain since 2014.
Jedinak burst on to the scene with Crystal Palace a few years back and was named the Asian International footballer of the year in 2014.

After participating in the 2010 and 2014 World Cups, this will be the midfielder's final chance to play for the national team at this level.
