Middlesbrough target Neven Subotic has opened the door to a January move to the club after returning to full fitness
The centre-back had agreed a €10m move to Boro in the summer, but a medical issue came to the fore and the move was shelved although he has not ruled out the deal eventually going through.
“This is an option,” he told German publication Bild. “Before then there is still a bit of time. My concentration at the moment is if I do not play games and get on the pitch, I cannot offer anything for Borussia Dortmund or any other club in the world. That’s why this is the most important thing now.”
