He scored 11 goals and provided four assists in 41 appearances across all competitions last season.
Brandt is now in the final weeks of an expiring contract, and it is already confirmed that he will leave Borussia Dortmund as a free agent this summer.
He has been linked with Arsenal, Barcelona, Roma, Aston Villa, Fenerbahce, Bayer Leverkusen and Atletico Madrid over the course of the season.
The Yorkshire Evening Post now reports that Leeds United have shown interest in Brandt, with the English club exploring the possibility of signing him on a free transfer.
Leeds finished 14th in the Premier League last season, while Dortmund finished as Bundesliga runners-up.
The attacking midfielder has scored three goals and provided three assists in 48 caps for Germany.
A move to Leeds would represent a significant step down in profile for a player who has spent the past six years as a regular contributor for one of the Bundesliga's leading clubs, but his contract situation makes him an unusually attractive free-agent option for clubs across multiple leagues this summer.
Brandt joined Dortmund from Leverkusen for around €25m and has made well over 200 appearances for the club, contributing to domestic cup success and regular Champions League involvement during his time at Signal Iduna Park.
His departure represents the end of a significant chapter for both player and club, with Dortmund losing a versatile attacking option without receiving a transfer fee in return.
Whether Leeds can convince Brandt that a return to Premier League-adjacent stability represents the right next step remains to be seen, with several of his other suitors offering Champions League football that Leeds cannot currently match.
