#2 Saul Niguez (Atletico Madrid)
Still only 23-years-old, Saul is already talked about as a potential matchwinner for Spain in Russia 2018. Still not sure of his best position, Saul is capable of playing as a midfielder and on both flanks. He even had an appearance as a full-back this season.
His ability to read the play and intercept passes make him well-suited to a number of defensive roles, while his technical skills, dribbling ability, and stamina has seen Simeone already use the Spaniard in a number of attacking roles.
One of Simeone's most trusted players, Saul is tipped to be among the next generation of world-class superstars. Having made the majority of his appearances from the central midfield role, Saul could soon turn out to be a top-class box-to-box midfielder for both Spain and Atletico Madrid.
Saul has all the ingredients to become a household name in the future.
