#4 Kalidou Koulibaly (Senegal)
The Napoli centre-back was born and raised in France by Senegalese parents and was therefore eligible to play for both the Senegalese national team and the French national team. After playing for France at the U-20 level in 2011, Koulibaly joined the Senegalese senior side in 2015.
He joined Italian side Napoli on 2nd July 2014 and has made 164 appearances in 4 seasons. For the national side, he has made 22 appearances and was a part of the Senegal squad at the 2017 Africa Cup of Nations.
Standing 1.95 meters tall, Koulibaly is known for having aerial prowess. He is not only physically strong but also a very versatile player as he can play at any defensive position in a 3 or 4 man defensive lineup. His ability to play as a centre-back or a fullback has made his fans give him the nickname 'The wall'.
At the 2018 FIFA World Cup Koulibaly will play a vital role for his side in the defence and will look to give the opposition attackers a tough time finding the net.
