#4 Matthijs de Ligt

There are widespread debate on whether De Ligt is the most promising young player in the world at the moment. And why not? At 19 year old, the young Dutch has shown all the hallmarks of a complete defender and proved himself against toughest opponents.
Calm and composed, De Ligt's excellent technique with the ball is a bonus. There are almost no criticisms when it comes to his brilliant defensive abilities. He has proven that he can excel against the top forwards in the world although facing Real Madrid in the UEFA Champions League will be another huge test.
Despite being top of the table at La Liga, Barcelona has conceded the most number of goals (19) and tied with Real Madrid when it comes to the worst defense among the top 5 teams. With an injured Umtiti, Gerard Pique and the Barcelona defense left ample of spaces for the rivals to exploit which is quite evident.
Securing a top talent like De Ligt will once again improve the squad depth of Barcelona and strengthen their rear guard for years to come.
