Borussia Dortmund could be about to receive a hammer blow from Bayern Munich, with their captain Mats Hummels looking poised to join the Bavarian club in the summer.

Borussia Dortmund chief executive Hans-Joachim Watzke expects the German international to join Bayern, given that Hummels has a deep rooted connection with the club.

Hummels came through the Bayern ranks as a youth player – but failed to break into the first team. He then moved to Dortmund in 2008 and has firmly established himself as a key component of the team.

Hummels’ family and girlfriend are from Munich, and so is the player himself, and these reasons will influence Hummels decision to move to Bayern, according to Watzke.

“I believe that if he (Hummels) goes, it will be in the direction of Munich,” said Watzke.

“He still has unfinished business with the club. His father, his mother and his brother all live in Munich.”His girlfriend comes from Munich, he’s from Munich too – so a whole lot of components have already come together.”

“We have to accept when someone like Mats, who has already played for Borussia Dortmund for eight years, is 27 and would come to think: ‘Am I going to play for Borussia Dortmund for my entire career, or will I do something else?'”

However, Watzke told Munich-based newspaper Sueddeutsche Zeitung he would “fight for Mat, like I have never before fought for a player.”

Watzke is also resigned to losing either Manchester City bound player, Ilkay Gundogan and Henrikh Mkhitaryan – who are out of contract in June 2017.

However one player who could make a surprise return to Westfalenstadion is Mario Gotze.
