As with Bochum, Fortuna Köln are familiar opponents for Bayer 04 in friendly matches. The last time the two teams met was in November last year with Leverkusen winning 1-0 at the Haberland Stadium. The goalscorer was Kai Havertz who, five days earlier, had become the youngest ever player to make his debut for the Werkself in the Bundesliga match against Darmstadt 98. Back then, Bayer 04 played Fortuna without 15 internationals and this time it will be nine – plus the two U19 players Sam Schreck and Atakan Akkaynak. The injured Charles Aránguiz (Chile) and Tin Jedvaj (Croatia) are unable to play for their countries this time round.
Head coach Heiko Herrlich will again use the opportunity against Köln to give time on the pitch to players in his squad who have not appeared much recently – such as goalkeeper Rambo Özcan, Stefan Kießling, André Ramalho, Vladlen Yurchenko and Marlon Frey. Fortuna Köln have had an excellent start to their third division campaign and are currently third in the table behind Paderborn and Magdeburg after eleven games. The team coached by Uwe Koschinat have only lost one game and they secured a 3-1 victory in their last match at Großaspach.
Bayer 04 have arranged another friendly for the third international window of the season against MSV Duisburg on 9 November.

Bayer 04 Leverkusen have appointed Carles Martínez Novell as the new head coach. The 42-year-old Spaniard worked for FC Toulouse in the French Ligue 1 until the end of the season. Martínez finished last term in ninth place with the club from the south of France. He will take over the Werkself on 1 July 2026 and has signed a contract to 30 June 2028. Martínez, whose contract with Toulouse expires at the end of the month, succeeds Kasper Hjulmand at Leverkusen, who is leaving the club after one season.
