Mats Hummels (Borussia Dortmund)
Projected value: £47m
German defender is one of the best in the business and whilst he has long been linked with a Westfalenstadion exit the fact that his side sits near the Bundesliga relegation zone, and seem unlikely to secure a Champions League berth for next term, would surely mean the 25 year old would be liable to leave Borussia Dortmund.
Arsenal are said to be Hummels main suitors and Arsene Wenger may well be ready to fork out a massive sum for the former Bayern Munich man.
