Marcel Schmelzer
Trained at Borussia Dortmund, Marcel Schmelzer made his debut with the reserve team in Regionalliga Nord in 2007. A year later, he made his professional debut in the Bundesliga at the age of 20, replacing the Brazilian Dedê, who was the regular starter on the left side of the defense. He only played in 12 matches during his first professional season, but in the following season, 2009/2010, he firmly established himself as the left-back, quickly gaining recognition for his work rate on the field.
