Boateng is basically an improved, fast, black, inform Hummels with better tackling, equal passing but a bit lesser heading.
Also Less injury prone, less error prone and overall just in much better shape. Even if Hummels would be in his best form, i think Boateng would have the edge because he is unreal with Benatia next to him and Neuer behind him at the moment.
What's with us making bids for players who are no way gonna move?
