It keeps getting better for Arsenal in the Champions League.
After back-to-back wins, the Gunners face next opponents Borussia Dortmund with their coach banned.
Dortmund coach Jurgen Klopp will be absent from the touchline after UEFA extended his ban on Thursday.
He was sent to the stands during the German side's 2-1 opening defeat at Napoli following an ugly confrontation with the fourth official.
And UEFA's control and disciplinary body have decided he must spend an extra match away from the touchline.
