This is another player who Roberto Mancini will be fully aware of his talents. This player not renowned for his attacking exploits but his efficiency at the back. This centre back has heralded the steel in defence for Borussia Dortmund and has been a key player in everything that has been good for the German Champions this season. The whole group found Dortmund an impossible prospect to break down and Hummels has to take huge credit for this. He left Bayern Munich as a youngster to join them and has always been tipped for the top. Mancini may have a solid defence already but in Hummels he could find the true defensive partner Vincent Kompany deserves.
