1st. Naldo - Despite strong defensive performances from Bayern Munich, Borussia Dortmund and Gladbach this season, it has been Wolfsburg’s central defender Naldo who has impressed the most this season. The towering defender is at the peak of his career and showing himself as one of the league’s best.
2nd. Jerome Boateng - If Naldo is the most in-form defender in the Bundesliga this season, then Bayern’s Jerome Boateng is potentially the most improved over the current campaign. Rarely rated by those outside of Munich, the German international has dug in and cemented his spot beside Dante in one of the best defenses throughout the continent.
3rd. Mats Hummels - Despite Dortmund's shaky run this season, one of the small, if not insignificant silver linings for Jurgen Klopp has been the slow and steady return to form for Mats Hummels. The German international was unfortunate to pick up an injury late last year which, along with the injury to Neven Subotic, derailed any hope of catching Bayern. Yet Klopp will just be happy to know he has his old defender back.
4th. Tony Jantschke - Tony Jantschke isn't technically an out and out centre-back this season with half his time spent on the right flank for Gladbach. Yet no matter where he ends up in the Foals' back line, his talent and ability to keep a cool head take centre stage. Lucien Favre's side have one of the best defensive records in the league this season and Jantschke can take plenty of credit for it.
