The son of Klopp’s wife Ulla Sandrock, 35-year-old Dennis, is set to become a father.

Speaking on Viaplay Sport Polska, a jubilant Klopp said: “I’m going to be a grandpa!”

Klopp and Ulla got married in 2005 after meeting at a pub during the Munich Oktoberfest.

The pair do not have any children together, but have sons from each of their first respective managers.

Klopp’s son, 34-year-old Marc, gets along well with Dennis according to Bild.

Ulla has been dubbed “the First Lady” of Bundesliga thanks to her charitable actions while Klopp worked in Germany.

She is also a children’s novelist, publishing her first book – “Tom and the Magic Football” – in 2008 before a sequel followed two years later.

Additionally, Ulla has worked as a teacher in Kenya and as a nurse in Nairobi.
