Newly promoted Middlesbrough are interested in signing Borussia Dortmund defender Neven Subotic, alongside fellow Premier League teams Stoke and Sunderland, according to reports from the Daily Mail.
The Serbian international is available for £6.5 million, but the Premier League trio could be left frustrated in their pursuit of the 27-year-old as he fails to meet the required criteria for a work permit, due to not playing for his country since 2013.
Subotic announced he would be leaving Dortmund on social media site Facebook, after falling out of favour under Thomas Tuchel, he said: “Dear friends, football is an important part of my life. I love it and I can’t be without it.
“I am in the best age for a football player and I want to use my time to improve myself and my team every day and I want to have the feeling I am needed and I can give everything for my club. That is what I am thinking about.
“I do not want to earn my money on the bench, but to be an active part of the history like I was until last year. I hope you can understand that.”
The German club has already seen Mats Hummels, Ilkay Gundogan, and Henrik Mkhitaryan leave the club, joining Bayern Munich, Manchester City, and Manchester United respectively.
Subotic would bring a wealth of experience, accumulating over 300 appearances with Mainz and Dortmund, winning two Bundesliga titles, One German cup, and two German Super cups. At 6’4″ the Serbian is a powerful figure in defence and he provides an attacking presence at set-pieces, netting 25 goals during his career.
