UEFA missed their appointment.
After the match against Celtic, their officials had arranged to meet with Dortmund's press officer, Joseph Schneck, the next day.
But the next day, they called to say there had been a change of plans and rescheduled.
The UEFA Europa League match was on a Thursday night. Since they didn't come on Friday, one couldn't expect the UEFA staff to work overtime on Saturday and Sunday.
Besides, Bundesliga matches were on the weekend, so Wang Shuo wouldn't have been available for them anyway.
So, it was postponed until the following Monday.
On the weekend, in the 12th round of the Bundesliga, Dortmund faced Werder Bremen in a fierce away match.
Starting for Werder Bremen was Marco Marin, whom Wang Shuo had known from his time in the 2nd Bundesliga when Marin played for Borussia Mönchengladbach.
It was his combination play with the number 11, Mesut, that led to a goal against Dortmund during a fast break in the 36th minute.
