Michael Olise will miss Bayern Munich's upcoming Champions League clash against Arsenal due to a suspension following a controversial sending-off. The incident occurred during a thrilling 3-3 draw against Viking in Norway, where Olise received two yellow cards in quick succession. His dismissal was prompted by a professional foul followed by throwing the ball into the face of Viking captain Zlatko Tripic.

In the match, Bayern Munich had managed to come back from a 2-0 deficit to take a 3-2 lead, thanks to a brace from Harry Kane and a goal from Luis Diaz. However, the momentum shifted dramatically after Olise's red card, allowing Viking to equalize through substitute Herman Haugen.

Bayern's manager Vincent Kompany expressed his disappointment, stating, "This red card was super dumb... you can see in [Michael's] eyes that he's sorry about it and that he regrets letting the team down."

In other Champions League action, Anthony Gordon netted his first goal for Barcelona, contributing to their 4-1 comeback victory over Galatasaray in Istanbul. After trailing following a first-half goal from Aleksey Batrakov, Barca equalized just before halftime through Joao Cancelo. Fermin Lopez put them ahead shortly after the break, with Gordon extending the lead before Karim Adeyemi sealed the game in the 65th minute.
