The report says Groß did not make his senior Germany debut until his early 30s, yet collected 19 caps and featured in two major-tournament squads. His value was built on calm passing, tactical discipline and set-piece quality rather than headline-making status.
“That was it for me after the World Cup,” Groß said, signalling that the decision had already been made. The report also says he was left out of Klopp’s next international group, adding clarity to a retirement that might otherwise have remained unspoken.
Groß’s Germany exit comes alongside an encouraging return to Brighton after his spell at Dortmund. The report says he has re-established himself as a central figure under Fabian Hurzeler, helping the club make a strong start to the Premier League season.
The update credits him with a productive opening run, including goals and assists, and places him at the heart of Brighton’s win over Arsenal. Those contributions underline the contrast: his international career is closing, but his club influence remains substantial.
“At 35, it is time to wish the new generation nothing but the best,” Groß said. He added: “I still enjoy football at club level, but Germany are going through a transition right now - and I will keep my fingers crossed.”
Groß reportedly expects “an awful lot” from Klopp. For the new Germany coach, replacing experience with energy will be a central challenge. Groß’s departure may accelerate that process, but it also removes a reliable voice from the dressing room.
The next international window will show whether Klopp’s younger midfield takes shape quickly. For Groß, the immediate storyline is Brighton: the coming Premier League fixtures will test whether his impressive return can drive an ambitious season.
