The Germany international has yet to recover from muscular problems related to his World Cup campaign but he says there is no cause for alarm among BVB fans
The Germany international has not been able to play any part in his club's pre-season preparations as he is struggling with muscular problems related to his participation in this summer's World Cup.
While he refused to be drawn on when exactly he will be fit to return to action, Hummels, who battled a knee injury in Brazil, reassured Dortmund fans that his unexpectedly long lay-off is nothing to worry about.
"I can still feel the effects of my injury from the world Cup final, but it is nothing serious," the 25-year-old is quoted as saying by Bild.
Meanwhile, Hummels has been touted as a possible successor to Sebastian Kehl as Dortmund captain and he admitted that he would be honoured if he is asked to accept the job by Jurgen Klopp.
"That's up to the coach," he pointed out. "I would love it but am accustomed to taking responsibility even without the captaincy."
