And he will now pursue his career with the Premier League new boys, who reportedly pipped Tottneham to the signature of the highly rated centre-back.
"Leeds United are pleased to announce the signing of Robin Koch from Bundesliga side SC Freiburg for an undisclosed fee," the Whites revealed in a statement published on the club's official website on Saturday.
"The 24-year-old has signed a four-year deal at Elland Road, running until the summer of 2024."

After losing out in the Championship play-offs in 2018-19 during Argentine coach Marcelo Bielsa's first season at Elland Road, having led the table for a large part of the campaign, Leeds ensured their return to the top flight after a 14-year absence this summer by finishing top of the English second tier, 10 points clear of nearest challengers West Brom.
Koch is the side's eighth new face of the current window, following hot on the heels of Rodrigo who became the club's record signing when he completed a move from Valencia earlier on Saturday.
Former Lorient goalkeeper Illan Mesler has also arrived at the West Yorkshire team, who have additionally signed a number of young faces including ex-Arsenal trainee Sam Greenwood and Fulham teenager Cody Drameh.
Leeds mark their return to the Premier League with a baptism of fire, travelling to Anfield to take on runaway 2019-20 champions Liverpool on September 12.
The Whites then face Fulham and Sheffield United before hosting Manchester City in the fourth round of fixtures on October 3.
