Germany beat Serbia, but Klopp’s first tournament threatens to be a major disappointment
In Belgrade, Germany saw off Serbia fairly comfortably as Jürgen Klopp's side beat the hosts 1-3.
Ajax goalkeeper Marc ter Stegen started in goal for Germany. Florian Wirtz, Kei Havertz and Joshua Kimmich were also named in the starting XI.
Wearing the captain's armband, Dusan Tadic started up front for Serbia in a 5-3-2 formation.
Serbia fell behind inside three minutes when Srdan Babic headed a corner past his own goalkeeper.
Ten minutes later, Florian Wirtz made it 0-2. Havertz missed a big chance, but the Liverpool midfielder was on hand to score from the rebound.
Germany dominated the rest of the first half with 86 per cent possession. Havertz and Jonathan Tah both came close to making it 3-0.
Shortly after the break, Kimmich sent Brajan Garuda through. The RB Leipzig forward finished calmly after a fine dribble.
Babic quickly pulled one back to make it 3-1, scoring for Serbia after his own goal three minutes in.
Despite creating several good chances as they improved, Serbia lost Vanja Dragojevic to a red card for a hard tackle on Kimmich. Germany then regained the initiative.
Andrija Zivkovic also saw red late on.
Following the Netherlands' emphatic win over Greece (7-0), Germany now have little chance of reaching the Nations League quarter-finals. They must either beat the Netherlands 15-0, or beat the Netherlands and hope Greece fail to beat Serbia.
