Christian Pulisic and his Borussia Dortmund teammates testified on Wednesday at the trial of the man who admitted setting off three explosive devices as the team bus headed to a Champions League match in April 2017.

Pulisic appeared alongside teammates Roman Burki, Sokratis Papastathopoulos, Raphael Guerreiro, Shinji Kagawa, Nuri Sahin, Lukasz Piszczek and Julian Weigl.

"It was just a normal game," Pulisic testified, recalling the hours before the first leg of the Champions League quarterfinal against Monaco at the Westfalenstadion.

"As soon as we left the hotel, I heard a loud bang. I didn't know what it was at first. But Roman, who sat next to me, tried to drag me under the table."

When asked about the mental impact of the attack, Pulisic said: "I had problems during the first weeks, yes. But now it's much better."

The suspect, charged with 28 counts of attempted murder, has claimed he did not want to injure anyone but rather create a "terror scenario" that would lead to a drop in the valuation of Dortmund's shares from which he hoped to profit.
