Borussia Dortmund boss Jurgen Klopp will have to serve an additional touchline ban when his side take on Arsenal in the Champions League.
The 46-year-old had initially been banned from Tuesday night's 3-0 win over Marseille for angrily confronting a fourth official during his side's 2-1 defeat to Napoli on September 18.
However, upon review, UEFA have decided to extend his suspension by one match, meaning that the German coach will have to sit in the stands at the Emirates later this month.
Klopp acknowledged his actions after the match against Napoli by saying that he acted like a "clown".
