Augustin played 48 minutes before being sent back to Leipzig on June 30, before Leeds won promotion.
Now, Leipzig claim Leeds have to pay €21m.
He struggled for minutes in 2018/19 and left for Monaco, where he rarely played before joining Leeds on loan in January.
His time at Leeds has been blighted with hamstring injuries.
Leipzig will argue that given the fact that Leeds won promotion at the end of the season, they are contractually obliged to pay the €21m.
Leicester, for example, signed Ryan Bennett on loan from Wolves in January with a purchase option being triggered if he makes 5 starts.
Leeds will be looking to save vital funds that could be used to bring in starters and players who are better fits for Bielsa.
Either way, this case is likely headed for FIFA and perhaps even CAS.
