Hummels had said after Dortmund’s defeat to Bayern in last Saturday’s DFB Cup final in Berlin that he did not want to sign the deal until he had played his last match for BVB. That time has now come, and both the player and his new club have expressed their happiness that the transfer has gone through.

"We’re delighted to be able to welcome Mats back to FC Bayern," said Karl-Heinz Rummenigge, the Reds’ executive board chairman, in reference to the 14 seasons Hummels spent with Bayern growing up. "We’re improving our side not just with a world-class defender but also with a player who doesn’t shirk responsibility, and who came through the youth ranks with us.“

Hummels excited

The Bergisch Gladbach-born defender first joined FC Bayern in 1995 at the age of six and represented the club at all youth levels. He made his Bundesliga debut in May 2007 under Ottmar Hitzfeld, but joined Borussia on loan in January 2008, eventually moving to North Rhine-Westphalia permanently six months later.

"It was obviously very tough for me to leave Dortmund, just like it was tough back in 2008, when I went the other way," said the 27-year-old. "Now i’m just looking forward to everything that awaits me at Bayern. I’m very excited."

Hummels made a total of 225 Bundesliga appearances for Dortmund, scoring 19 goals and winning the Bundesliga in 2011 as well as the league and cup double in 2012.
