#4. Erik Durm
The baby-faced full-back made his name at Klopp's Dortmund after coming through the ranks at Mainz. Pacey and explosive, Durm was phenomenal and played a crucial part in Dortmund's domestic and European success in the 2012-13 and 2013-14 seasons. His good run of form led to him making his first appearance for the German National team in their last game prior to naming the final squad for the World Cup, a squad he was subsequently included in, just a day after making his national team debut.
Durm was an unused substitute in all the games during the course of the World Cup. He provided competition to Benedikt Howedes, Phillip Lahm and Mathias Ginter for the full-back slots. Capable of playing on both flanks, Durm is a predominantly an attacking full-back who can tear down the flanks and is a decent crosser of the ball.
Considering the fact that all seven of his appearances for Germany came during the 2014 calendar year, Durm stands a very low chance of making the cut for the 2018 World Cup. He has fallen down the pecking order at Dortmund too with Dan-Axel Zagadou, Raphael Guerreiro, Jeremy Toljan and Marcel Schmelzer all above him in Peter Stoger's list.
