For a player with ten months remaining on his contract, this is a sum Freiburg will be happy to receive.
However, it has become clear that Marcelo Bielsa’s Leeds have won the race for the talented German international.
Leeds turned to Koch after Brighton rejected multiple bids for Ben White who spent last season on loan at Elland Road.
And Koch said his goodbyes to his teammates on Friday at their Austrian training camp.
Before he joins up with the Germany national team on Monday, there should be a stopover in England.
Koch has made 82 appearances in the Bundesliga for Freiburg, scoring four goals.
