None, even though I searched for a few rumors about them, there were none. There were no rumors regarding Dortmund signing another great player for this transfer market. Instead, I heard rumors about their central midfielder, Marcel Sabitzer, being linked to Fenerbahce. However, no further discussion about this.
Usually Dortmund always makes a surprise in the transfer market because it always manages to sell players at a very fantastic price. But for the transfer market this season looks more quiet, not just about selling players but there is no big movement about changes in the squad in undergoing next season. Marcel Sabitzer has been lent by a number of clubs before and maybe it's time for the player to be sold permanently to other clubs. There is nothing interesting in Dortmund now and I think they don't seem to target anything next season if you look at their current performance.
