Borussia Dortmund are believed to have lined up a number of potential replacements for Barcelona-bound playmaker Ousmane Dembele, with one of them having featured heavily on Barcelona's wishlist in the past.
At this moment in time there are believed to be four names on Dortmund's list of options. With English news outlet 'Sky Sports' reporting that Athletic Bilbao forward Iñaki Williams heads the list.
Wililiams is joined by Lyon's Maxwel Cornet and Fiorentina's Federico Chiesa, though the final option is by far the most curious.
Gremio playmaker Luan is the man in question, with Brazilian radio station 'Radio Gauíba' reporting that the German side are seriously interested in a move for the 24-year-old, who has spent most of the summer being linked with a move to Liverpool.
The versatile forward was chased by senior Barca officials during the January transfer window but a move never came to fruition.
Dembele remains a Dortmund player at this moment in time but the German side have already given up hope of keeping the French international after he all but went on strike in an attempt to force through a move.
It seems a question of when, rather than if he will complete his move to the Camp Nou.
