Borussia Dortmund's flight to London for Wednesday's Champions League fixture against Tottenham was delayed by over an hour after a player forget his passport.
And the culprit was an Englishman - winger Jadon Sancho.
The 18-year-old realised his mistake when he arrived at the airport and needed to return home.
Dortmund have arrived in England and will train at Wembley on Tuesday before the first leg of the last-16 tie.
