The Champions League is back this week and Borussia Dortmund are in London for a game against Tottenham, the runners up from Barcelona's group.
But the German club's fligth to the English capital had to be delayed because of Jadon Sancho -- who is returning to his homeland.
England international Sancho forgot his passport and was not allowed on the plane with his teammates. To do so, he had to quickly return home, pick up his passport and get back to the airport.
Lucien Favre's side, who lead the Bundesliga ahead of Bayern Munich, face Tottenham on Wednesday at Wembley, with Ajax hosting Real Madrid in the night's other game.
