#2 Sergio Ramos
Sergio Ramos is one of the best defenders at the 2018 FIFA World Cup. He is a no-nonsense defender who has a great tactical mind, positional sense and is superb at heading the ball into the opposition's goal during set pieces.
Being the captain of the Spaniards, Ramos has led the team exceptionally and has always motivated players who have made mistakes. Despite Spain conceding 3 goals against Portugal in a 3 all draw, Ramos gave a superb defensive display in that match and was quite effective against his Real Madrid teammate Cristiano Ronaldo. Against Iran, Ramos was successfully able to negate the few threats thrown by them in Spain's penalty area.
Ramos will stand like a rock between Morocco and the Spanish goal. Hence, it will be difficult for the adventurous and attacking style of Morocco attackers to get past Sergio Ramos.
