Borussia Dortmund midfielder Ilkay Gundogan fears that it could be a while before he will be fully pain-free again as he continues his recovery from a back injury.
The Germany international has not featured for BVB since their Bundesliga opener against Augsburg in August but recently resumed squad training again.
Nevertheless, Gundogan - who has been told by the club to make a decision over his future sooner rather than later after entering the last 18 months of his contract - has made it clear that his physical problems are not over just yet.
"I'm still having pain," the 23-year-old is quoted as saying by Bild.
"The things that I've been doing so far are going fine but there will be moments where I will have to get used to the intense work again.
"I am not top fit just yet and I'm not completely pain free at the moment. I still have pain in my hip, calf and shin.
"My main objective is to get fully healthy again. Once I've achieved that, I want to give my all again."
Dortmund resume Bundesliga action at home against Augsburg on January 25.
