Mats Hummels, Borussia Dortmund
The departure of Rio Ferdinand and Nemanja Vidic this summer means that the side’s central defensive partnership of the last eight-and-a-half years is set to be broken down in one fell swoop.
Therefore the heart of defence is desperate for recruitment, with doubts remaining over the credentials of both Phil Jones and Chris Smalling in the role.
There would be no such concern over Hummels however, with the Germany international considered to be among the best centre-backs on the planet and is a stalwart for both club and country.
