Borussia Dortmund rejected a €12m transfer fee for winger Jacob Bruun Larsen during the most recent summer window following the youngster's loan spell with domestic rivals VfB Stuttgart.
The Denmark Under-21 international was on loan with Stuttgart last season and despite making just four appearances, Bruun Larsen still impressed the club's hierarchy during the second half of the campaign.
Stuttgart chief Michael Reschke, formerly of Bayern Munich, confirmed that the club were willing to smash their transfer record in the hopes of landing Bruun Larsen during the summer, only to be rebuffed by Borussia Dortmund.
