There's nothing to say he has from a quick Google. He did previously play for them in 2013 though. And his dad played for them I believe.
That's too much to translate word for word, but in summary it's saying what we've already heard - that Nürnberg are interested in him, but they'd prefer a loan rather than an outright purchase. Hertha BSC however want to sell him outright. There's no mention of Barnsley or any other club in the video. It also talks about his attributes as a footballer, which are his pace, technical skills and dribbling ability, together with finishing. Negative points are that he's not really had a look-in at Hertha and hardly plays, so his confidence and experience at a high level is missing.
so really it's old news. It was mentioned about them wanting to loan and that Hertha wanted to sell, and this was a good few days ago. Time will tell.
Thanks Stahlrost. It said it was a new video so I thought it might have been new news, not old news. I knew that he was a former player of theirs so I thought he may have gone back on loan.
