#2. Mats Hummels - €38.00 million
Undoubtedly one of the best centre-backs in the world right now, Hummels moved back to his youth club Bayern Munich after 8 seasons at Dortmund where he was eventually made the captain. Even though he had a year left on his contract, Dortmund extracted a hefty €38 million from Bayern thus making him the 2nd most expensive player in Bundesliga history as the Bavarians continued their practice of gutnig rival squads for their best players.
The world cup winner with Germany in 2014 is a large, consistent, and physically strong player is known for his powerful tackling and strength in the air. He's excellent in game reading and intercepts loose balls with ease. One of the few technically gifted central defenders of his generations, Hummels is tactically flexible and can be used as a defensive midfielder. His composure, elegance, on-the-ball abilities and confidence in possession have drawn comparisons with compatriot Franz Beckenbauer.
