The England international has been linked with a move away from Signal Iduna Park, and Dortmund are searching for a potential replacement.
According to Belgian publication, HLN, Die Borussen have identified Super Eagles and Club Brugge winger, Emmanuel Dennis as a potential replacement for Jadon Sancho.
Sancho could leave this summer with Manchester United, Chelsea and Liverpool reportedly interested in the services of the 19-year-old.
As a result, Dortmund are interested in Dennis who caught the attention of the public eye after scoring twice in Club Brugge's 2-2 draw against Real Madrid at the Santiago Bernabeu in September's Champions League clash.
Dortmund may face competition from Newcastle who were also interested in the Nigeria international during the January transfer window and could make a move for him again this summer.
Dennis joined Brugge from Zorya Luhansk in 2017 for €1.30m, but he is now valued at €12.00m. The 22-year-old has featured 30 times for Blauw-Zwart this season, scoring eight times and registering two assists.
He made his national team debut in Super Eagles 2-2 draw against Ukraine in the international friendly match between the two sides last September.
