#10. David Alaba
David Alaba has made himself into one of the best full backs in the world and a star player for Austria. Part of the modern full backs role is to be as good in attack as defence and Alaba is a perfect example of how it should be done. The modern position however requires a lot of stamina as the player is expected to get up and down the whole length of the pitch on a regular basis in order to help with attract but not be missing in defence. He is a great player for his technical ability, but helped by his great stamina.
