10 players Bayern Munich regret selling

#6 Mats Hummels

Hummels returned to Munich after a successful spell at Dortmund

Brought through the youth team at Bayern Munich, Mats Hummels played second fiddle to Holger Badstuber before a loan move to Borussia Dortmund in 2007 as an 18-year-old. Just two years later, Borussia Dortmund made a permanent move for Hummels, where he then went on to establish himself as one of the Bundesliga’s leading defenders.

Instead of nurturing Hummels, Bayern Munich brought in Brazilian defender Breno, who went on to fail while Badstuber failed to get a lengthy run in the starting XI due to injuries.

In his time at Borussia Dortmund, Hummels won two consecutive Bundesliga titles under Jurgen Klopp as well as the 2012 DFB Pokal before adding the World Cup to his honours list just two years later.

Granted, Borussia Dortmund haven’t been able to challenge Bayern Munich following the departure of Klopp in 2015 but had the Bavarians kept Hummels rather than selling him in 2009, it could be a totally different story.

Bayern may not have just dominated the league, but conquered Europe.

July 2016 saw the return of Hummels to Bayern Munich. In his 42 Bundesliga fixtures since then, the German centre-back has gone from strength-to-strength, making himself one of the best, established defenders in world football.
