Borussia Dortmund have confirmed the departure of Mats Hummels after a combined 13-and-a-half years at the club.

Hummels initially joined on loan from Bayern Munich in January 2008 and went on to make 508 appearances across two spells with Dortmund, who he left in 2016 before returning three years later.

The decorated defender won back-to-back Bundesliga titles with the Black and Yellow in 2010-11 and 2011-12, while also helping them reach two Champions League finals.

The latter of these came earlier this month when Edin Terzic's side were beaten 2-0 by Real Madrid at Wembley.

During his second spell, Hummels made 367 Bundesliga appearances - 343 of which were starts - with Dortmund winning 216 of those and keeping 108 clean sheets along the way.

The decorated defender, who also won three Bundesliga titles with Bayern as well as the 2014 World Cup with Germany, is the club's second significant departure in as many days, with head coach Terzic resigning on Thursday.

"It was a huge honour and pleasure for me to have played for BVB for so long and to have been part of the journey from 13th place in January 2008 to what Borussia Dortmund is today," he told the club's official website.

"This club with its fans is something very special - and for me, much more than that. I would also like to thank all the BVB employees who do great work for this club and, of course, the countless great coaches and fantastic team-mates I have been able to experience here.

"I'll be cheering from afar and hopefully in the stadium, from time to time. I will miss you."

"In Mats Hummels, we are undoubtedly losing an outstanding personality, perhaps one of the last of his kind in football," sporting director Sebastian Kehl added.

"Mats has not only shaped BVB during his career, but has also taken the centre-back game to a new level worldwide. In addition, Mats is a real guy who challenges himself and others at all times.

"I thank Mats for his passion, for his will to succeed, also for his rough edges. Everyone at BVB wishes him all the best for his sporting and private future. Personally, I will always remain connected to Mats, whom I have held in high esteem for many, many years."
