Hummels says he's losing sleep deciding his Dortmund future
Mats Hummels says deliberating over his Borussia Dortmund future is giving him sleepless nights amid continued speculation of a move to England this summer.
Liverpool, Manchester United and Arsenal - along with Barcelona - are reportedly admirers of the Dortmund captain, but no bids have been lodged as yet.
"I've set a date [for my decision], but I'm keeping it to myself," Hummels told Sky Germany. "It's costing me half an hour before bed every night."
Hummels has spent more than seven years at Dortmund after initially joining the eight-time Bundesliga winners on loan from Bayern Munich in 2008.
The Germany international's father, Hermann Hummels, says his son faces a difficult decision regarding his future and admits a return to Bavaria could be on the cards for the Bayern Munich academy graduate.
"Mats is facing a tremendously important decision in his career, in his life," Hummels senior told Bild. "Dortmund is back among the top clubs in Europe, so the decision is so hard for him.
"If he should leave Dortmund, then he goes to one of the five or six top clubs. And to these clubs one is of course FC Bayern."
