The ex-Arsenal and Germany goalkeeper replaced Jurgen Klinsmann on the Bundesliga club's supervisory board in May 2020.

But Lehmann has left his position with Hertha for comments made regarding fellow former Germany international Dennis Aogo, who works for Sky Sports.

Lehmann appeared to accidentally send a WhatsApp text to Aogo, who posted a screenshot of the image via Instagram and captioned it: "Wow, are you serious? This message was probably not meant for me."

Hertha parted company with Lehmann and president Werner Gegenbauer said: "Such statements are in no way representative of the values that Hertha stands for. 

"We distance ourselves from all forms of racism and welcome the action taken by TENNOR Holding."

Lehmann, who also represented Schalke, Milan, Borussia Dortmund and Stuttgart during his playing career, has issued an apology to Aogo.

"In a private message from my mobile phone to Dennis Aogo, an impression was created for which I apologised in conversation with Dennis," he posted on Twitter. 

"As a former national player he is very knowledgeable and has a great presence and drives ratings to Sky."
