Stuttgart Starts Seimen Against Atletico in Champions League Test

VfB Stuttgart faced one of its toughest challenges of the UEFA Champions League league phase when Atletico Madrid visited the MHP Arena on Tuesday, October 20, 2026. Coach Sebastian Hoeneß sought a third consecutive victory in the competition, while goalkeeper Dennis Seimen made his Champions League debut against Diego Simeone's experienced Spanish side.

According to VfB Stuttgart's official lineup announcement, the hosts entered the third matchday with six points from two games and occupied fourth place in the league-phase standings. Stuttgart had defeated Viking Stavanger 3-1 and Slovan Bratislava 3-0, while Atletico opened with a 2-1 loss to Liverpool before beating Manchester United 2-0.

Stuttgart named Seimen, Ramon Hendriks, Josha Vagnoman, Angelo Stiller, Maximilian Mittelstädt, Chris Führich, Bilal El Khannouss, Jamie Leweling, Grischa Prömel, Jeff Chabot and captain Deniz Undav in its starting lineup. Compared with the 3-0 victory over Slovan Bratislava on October 14, Hoeneß made three changes, introducing Seimen, Mittelstädt and Leweling from the start.

Seimen, aged 20 years and 10 months, became the youngest goalkeeper to represent Stuttgart in the Champions League, according to the club. He had previously made his Bundesliga debut in a 2-0 away win at Paderborn on October 10, 2026. Mittelstädt also returned to the starting lineup for the first time since suffering a heel laceration.

Hoeneß described the encounter as a major occasion for the club and its supporters, emphasizing the significance of facing one of Europe's leading teams.

"It will certainly be a great occasion for all of us, for VfB and for the region," said Hoeneß, Stuttgart's head coach.

A victory would strengthen Stuttgart's position in the race for a place in the knockout rounds. The club had previously beaten Juventus 1-0 away in October 2024, its only victory over a team of comparable stature in the Champions League under Hoeneß, according to a report by dpa published by Berchtesgadener Anzeiger.

Stuttgart sporting director Fabian Wohlgemuth warned that Atletico's physical approach would demand considerable resilience from the German side.

"There will certainly be a lot of athleticism, duels and physicality coming our way," said Wohlgemuth, VfB Stuttgart's sporting director.

He characterized Atletico's style as "very masculine," referring to the team's aggression, experience and willingness to compete physically. Stuttgart would need to withstand that intensity without losing its composure, according to the dpa report.

The coaching contest also placed Hoeneß's measured approach against Simeone's famously animated touchline presence. The Argentine has led Atletico for nearly 15 years, winning two Spanish league titles and taking the club to two Champions League finals, both of which ended in defeat against city rival Real Madrid.

Atletico's pursuit of its first Champions League title remained a central ambition, with this season's final scheduled for the club's home stadium, the Estadio Metropolitano. Simeone's teams have repeatedly challenged Spanish rivals Real Madrid and Barcelona through tactical discipline, while his emotional touchline behavior has also drawn attention.

For Hoeneß, the match represented another milestone in a rapid managerial rise. After making his Bundesliga coaching debut with TSG 1899 Hoffenheim in summer 2020, he transformed Stuttgart from a team fighting near the relegation zone into a leading side and guided the club to the German Cup title in 2025.

Stuttgart's need for greater aggression had become a talking point after its Europa League round-of-16 elimination by FC Porto the previous spring. Striker Ermedin Demirovic had acknowledged that the team lacked a certain edge during that campaign, while Wohlgemuth indicated that the physical demands against Atletico could be even greater.

Demirovic entered the match after scoring four goals in the Champions League campaign, according to Stuttgart's official preview. The club hoped its home crowd and strong start to the league phase would help it challenge an Atletico side seeking another step toward European football's biggest prize.
