Nagelsmann, who had a contract until 2028, stepped down from the job on Friday, just four days after Germany's disappointing last-32 exit to Paraguay.In a statement, the DFB said discussions would begin with Klopp, the former Liverpool and Borussia Dortmund manager, while thanking Nagelsmann for his almost three-year stint.Klopp, who led Liverpool to Champions League and Premier League honours, is currently under contract as Red Bull's head of global football, but Sky Germany reports he has a verbal agreement which would allow him to leave to take up the Germany job.Nagelsmann's resignation comes a day after the 38-year-old was called into a three-hour meeting at DFB headquarters in Frankfurt to discuss his future.German tabloid Bild reported the coach was offered a severance package of seven million euros ($8 million), roughly one year's salary, to cut short his contract which was set to expire in 2028."The decision was anything but easy for me," Nagelsmann said in a statement. "My top priority has always been the success of the team. After such a bitter disappointment, it deserves the chance of a new beginning."Nagelsmann apologised to fans for the early exit."I am sorry and hurt from the bottom of my heart that we disappointed you and couldn't give you any more football nights at this World Cup."DFB sporting director Rudi Voeller said Nagelsmann "is and remains an excellent coach and I am convinced that he will continue to follow his path successfully".- Series of setbacks -
