#4 Pepe
Pepe was the Man of the Match in the Euro 2016 final, helping Portugal overcome France in a thriller. That remains his only international trophy till date and he will be looking to add the 2018 World Cup to his haul.
Pepe currently plies his trade with Besiktas after spending 10 years at Real Madrid but still has the ability to compete at the highest level. He played a major role in their qualifying campaign, helping them finish on top of the group.
The defender has been a part of 2 previous World Cup campaigns - in 2010 and 2014 - and considering the fact that he's currently 35, this is all set to be his final one.
