Japanese forward Soichiro Kozuki scored his first goal in his second appearance for Schalke in the German Bundesliga on Tuesday, while midfielder Wataru Endo also found the net for Stuttgart.

Kozuki scored the home side's only goal in a 6-1 defeat to Leipzig, slotting past the keeper in a one-on-one in the 56th minute, collecting a pass an instant before sprinting past Croatia's Qatar World Cup star defender Josko Gvardiol.

"It's a disappointing result and really frustrating. I'll prepare well for the next game," Kozuki tweeted.

The 22-year-old Kozuki in 2021 left Kyoto Sanga, who were then in Japan's second division for a team in Germany's fifth division. He earned a contract with Schalke at the end of 2022.

Schalke remain rock bottom having conceded a league-worst 41 goals in 17 games.

"There's no doubt we need to concede less. We want to discuss our tactics with the manager," said Schalke teammate and Japan captain Maya Yoshida.

Endo scored his third league goal of the season as Stuttgart drew 2-2 to Hoffenheim, curling home a first-time effort from the edge of the box to give the visitors a 2-1 77th-minute lead.

Stuttgart went a man down a minute later, however, and Andrej Kramaric leveled in the 90th minute for the hosts with his second goal of the match.
