Leeds United have announced their second signing of the day in defender Robin Koch.
Koch has agreed a four-year deal and moves for an undisclosed fee from Freiburg, just hours after Spain forward Rodrigo Moreno joined from Valencia.
Koch, 24, is a Germany international who has been included in their latest squad.
Over the last three seasons he made 87 appearances in all competitions, scoring five goals.
In 2019/20 he helped Freiburg finish eighth in the Bundesliga, winning 64.1 per cent of his aerial duels and having 32 shots in as many appearances.
