Bayer Leverkusen began their Champions League journey with a dominant 4-0 victory over Feyenoord, netting all their goals before half-time. Xabi Alonso's squad, who previously secured a Bundesliga and DFB-Pokal double while reaching the Europa League final, overwhelmed their opponents within the first 44 minutes at De Kuip.
Florian Wirtz made an impressive start to his Champions League career by scoring just five minutes into the match. Assisted by Robert Andrich, he found the bottom-right corner. Alejandro Grimaldo doubled the lead with a back-post finish after Jeremie Frimpong's assist, and Wirtz added another goal in the 36th minute.

Leverkusen extended their advantage to four goals just before half-time when Timon Wellenreuther inadvertently directed Edmond Tapsoba's header into his own net. This left Feyenoord facing one of their heaviest European defeats, matching a similar loss to Manchester City in 2017.
The emphatic win places Bayer Leverkusen third in the early Champions League standings. Their next challenge will be against Milan on October 1. Despite not adding more goals in the second half, this victory marks one of Leverkusen's largest wins in UEFA Champions League history.
Florian Wirtz was named Bundesliga Player of the Season as Leverkusen clinched the title last season. On Thursday, he transitioned seamlessly to Europe's top club competition. At just 21 years and 139 days old, he became the first German player to score twice on his Champions League debut.
Since the start of the 2020-21 season, only Bruno Fernandes has been directly involved in more goals (28) than Wirtz (26), who has scored 14 goals and provided 12 assists in major European competitions.
