Jurgen Klopp's wait for a first win in charge of Germany continued on Sunday as Dimitrios Kourbelis' second-half goal earned Greece a famous 1-0 victory in the Nations League.

Klopp was denied by Cody Gakpo's stoppage-time equaliser against the Netherlands in their Nations League opener, and his home debut at WWK Arena ended in a shock defeat.

Germany are third in Group A2 having taken just one point from their opening two games, with a home game against Serbia, who are also without a win, up next this Thursday. 

It took until the 25th minute for Germany to carve out their first clear-cut opportunity, but Younes Ebnoutalib was unable to steer Kevin Schade's dangerous delivery on target. 

Karim Adeyemi then fired over after being set free by Joshua Kimmich, with the Barcelona forward then forcing Konstantinos Tzolakis into making his first save of the match minutes later with a curling left-footed strike that was pushed behind. 

The hosts' dominance continued after the break, with Bambase Conte dispossessing Christos Zafeiris and seeing his shot saved by Tzolakis, with the Greece goalkeeper then on hand to keep out Ebnoutalib and Kimmich's free-kick. 

Greece came within inches of taking the lead against the run of play in the 67th minute through Fotis Ioannidis. Kimmich lost possession to Vangelis Pavlidis, who sent through Ioannidis, but his first-time attempt whistled past the left post.

But the visitors took the lead in the 74th minute when Christos Tzolis' deflected cross fell kindly to Kourbelis on the edge of the box. He skipped around Felix Nmecha before firing an effort at goal that took a knick off Kimmich on its way into the net. 

Serge Gnabry attempted to get his team back into the match, but his shot was held by Tzolakis, with Germany's possession yielding little in the shape of chances as Greece held on to go top of Group A2 with six points from their first two games. 

Plenty to ponder for Klopp

Ahead of sitting in the Germany dugout for the first time against the Netherlands, Klopp refused to make any promises of silverware and instant success during his time in charge, and this result proves there is still plenty of work for the former Liverpool boss to do.

Klopp made five changes to his team, and they were perhaps unfortunate not to find themselves in front after wasting a string of glorious chances, and their profligacy in front of goal was punished in the second half by Kourbelis. 

Germany's dominance with the ball was backed up by the metrics, too. Thanasis Androutsos had the most accurate passes of any Greece's outfield players that started the match with just 21, with the hosts also ending the contest with 75.5% possession. 

But the statistic that matters is the scoreline, and Greece will be delighted with their victory. They finished with an expected goals (xG) total of 0.77 from their eight shots, scoring with the only one they had on target, compared to Germany's tally of 1.34 from their 16 attempts.
