After not having succeeded in signing him during last summer, Borussia Dortmund are back tracking Turkish international centre-back Ömer Toprak (27), who's in turn more and more tempted to leave Bayer Leverkusen (after what would be 5 seasons and a half spent playing there). Especially if losing Subotic, Bundesliga giants are ready to submit their Westphalian side rivals a cash offer, amounting to around 15 million euros. Toprak has been tracked by Arsenal as well, in the recent past.
