The previous meeting at the legendary Celtic Park was convincing in terms of the result: After 90 minutes in ‘Paradise’, the nickname of Celtic’s home ground, the Werkself clocked up a clear 4-0 away win. “We earned that victory. We were effective in converting chances and were decisive in challenges,” said Gerardo Seoane at Wednesday’s pre-match press conference looking back at the encounter at the end of September. “However, there wasn’t a four goal difference in that match.”
The Swiss coach is expecting a tight match in the return game – also due to the upturn in performances and results for he visitors from Scotland. Seoane added: “They have put together a positive runs of results recently and focused their approach. The coach (Ange Postecoglou, ed.) has clearly made his mark on the team. They are now in a better ryhtym compared with the game in Glasgow.”
The 43-year-old Leverkusen head coach has an ever bigger choice of personnel in the third last double fixture week in 2021: 25 players were involved in the final pre-match training session on Wednesday morning including the recovering players Patrik Schick, Lucas Alario, Charles Aránguiz and Karim Bellarabi. “We’re confident these players have come through the worst stage and will soon be back on the pitch,” said Seoane.

Kerem Demirbay, who misses the Celtic game due to suspension for a red card, was not on the pitch unlike the injured Julian Baumgartlinger and Mitchel Bakker. The playmaker suffered a blow to the ribs in last weekend’s 1-0 home win against VfL Bochum. He is making use of his personal time off and is now doing rehab training.
Amine Adli joined head coach Seoane on the podium in the BayArena Media Centre on Wednesday. The Frenchman joined Leverkusen in the summer from FC Toulouse and has started five games on the bounce. “I feel at home in the dressing room and on the pitch,” declared the 21-year-old who scored his first Bundesliga against Bochum. “Nobody expected me to score with my head. (He laughs) But my first goal as a professional was a header. Perhaps that’s a good sign for the future at Leverkusen. I’ll be happy if that carries on.”
Adli is looking to build on his recent performances in the match against Celtic. The Europa League has definitely given the versatile attacker extra motivation. The France U21 international: “This competition is very important to us. We want to win all the games and then see where we end up.”
The situation ahead of the clash is clear for the Black and Reds: Three points against the third-placed Scots would win the group with a game to play. The new Europa League format – the team finishing top of the group avoids the next group stage – according to Seoane there is even more tension. “We want to secure our position in this situation. But we are focused on tomorrow’s game and not potential scenarios that might occur.”

Following the final match of the 2025/26 season, the prevailing feeling was naturally one of disappointment after missing out on qualification for the Champions League. The Werkself finished the Bundesliga in sixth place, meaning they'll start the 2026/27 campaign in the Europa League. "But to talk negatively about everything now because of that would be wrong," stressed captain Robert Andrich following the final game, knowing that the past year at Bayer 04 was marked, more than almost any other, by the start of a new era and the courage to change – and in particular, the belief in a positive direction. Everyone was aware this process would need time. The first part of the 2025/26 season review.
